Slab allocator update

Unused slabs which get recycled are no longer reinitialized from scratch if their chunk size matches what the allocator needed. If the chunk size matches, the list of available chunks is left unchanged, and just the various counters are reset.

Added __get_slab_stats() function.

Added support for global __slab_purge_threshold tuning variable.

Added a short test program for the slab allocator.

The malloc-test program was linked against the wrong object file in GNUmakefile.68k. Fixed.

+
+## What is this?
+
+This is my attempt to get Samba 2.2.x ported to the Amiga. My first Amiga port required *SAS/C* and a number of strange tricks had to be pulled to get it to support the kind of environment Samba needed. But with the introduction of Samba 2.2.x many of those tricks did not work any more, which is why I decided to attack the problem at the root, namely the runtime library.
+
+Because it was no longer possible to build Samba with *SAS/C* on the new Amiga platform, the idea came up to move development to the GNU 'C' compiler. This turned out to be a challenge due to its somewhat underdeveloped runtime library and header files. Eventually, I decided to rewrite that library from scratch.
+
+
+## What does it do?
+
+Using *'C' - A reference manual* (4th edition) as a reference I wrote a set of header files, then proceeded to implement each single function referenced in them. With few exceptions in the area of wide character support, the result should be a feature complete implementation of the ISO 'C' (1994) runtime library. The library was subsequently updated to offer functionality defined in *ISO/IEC 9899:1999*, also known as *C99*.
+
+Because Samba needs a few POSIX-like routines to be supported, the library functionality is complemented by a set of routines described in *Advanced programming in the Unix environment*.
+
+This is not a portable implementation of the library in the sense that you could move it from one 'C' compiler on one operating system to another. This is an Amiga specific implementation.
+
+The library supports floating point math, which, for the 68k platform, is limited to IEEE single and double precision or M68881 inline math. There is no support for the fast floating point (FFP) format or exclusive IEEE single precision. You either get double precision (IEEE math) or extended precision (M68881 inline math). What it is that you get is determined at compile time. Use the `IEEE_FLOATING_POINT_SUPPORT` preprocessor symbol to activate IEEE math code and the `M68881_FLOATING_POINT_SUPPORT` symbol for M68881 inline math.
+
+For the PowerPC platform, the library uses code borrowed from <a href="http://www.netlib.org/fdlibm/">fdlibm 5.3</a>, which is a portable library of arithmetic functions developed by Sun Microsystems which, for example, is also used within the Java platform.
+
+## What does it not do?
+
+This library is a departure from the typical 'C' runtime environments of the past which had to run on all AmigaOS releases, down to *Kickstart 1.1*. This very library was designed to take advantage of the routines available since *Kickstart 2.04* was introduced and virtually nobody ever put to use. This helps to cut the code size, and it also helps to keep bugs out of the library by falling back onto well-tested implementations. However, the catch is that the code won't run under *Kickstart 1.3* and below. But then these operating system releases have been obsolete for more than a decade, and you can always go back to a compiler environment which supports them.
+
+There is very little support for `amiga.lib` functionality. There is `NewList()`, `HookEntry()`, `CallHook()`, `CallHookA()`, the `DoMethod()` family, the *RexxVars* family, but that's all. If you need more, you would have to implement it yourself. Put another way, if you absolutely need functionality that is only found in `amiga.lib`, you really shouldn't need it in the first place.
+
+
+## Where does the source code come from?
+
+I originally thought that it might be helpful to piece this library together from various sources, such as the BSD libc. It turned out that this code was so 'portable' that it became much more complex than it ought to be. Also, some side-effects were present which considerably changed the behaviour of the library. For example, the BSD libc uses `bcopy()` as an alias for `memcpy()`, and unlike `memcpy()` is documented to, `bcopy()` supports overlapping copies.
+
+Eventually, I wrote virtually all the code myself, borrowing algorithmic ideas from the BSD libc and the *Manx Aztec 'C'* runtime library. Because I don't know much about the environment *GCC* expects, I borrowed code snippets from *libnix*, which was written by Matthias Fleischer and Gunther Nikl. This in particular concerns the integer and floating point math support, the `setjmp`/`longjmp` routines and the startup code. The M68881 inline math code comes from the `<math-68881.h>` file written by Matthew Self `(self [at] bayes.arc.nasa.gov)`.
+
+
+## Limitations and caveats
+
+There is hardly any documentation on the code I wrote. In part this is due to the fact that the code itself is very simple in design. It should speak for itself. However, to make a usable runtime library you have to have a user documentation as in *man pages* or *AutoDocs*. We will eventually have to have *AutoDocs* for this library.
+
+The exception handling in the math code is not particularly effective. For one part this is due to the fact that there is no exception handler installed by the runtime library when it starts up which could catch and process the error conditions the CPU or FPU generates. The idea was to provide for a portable runtime library with little to no assembly language involved. To make the exception handling complete, such code would be necessary.
+
+The library currently builds under *SAS/C*, but because the 'normal' program startup code is not utilized, the base relative (A4) addressing does not work. If you are going to test it, use the `data=faronly` option to compile the library and the programs.
+
+Different build *Makefiles* are supplied for use with *GCC*. There is a `GNUmakefile.68k` for the 68k platform and a `GNUmakefile.os4` for the AmigaOS4 PowerPC version.
+
+### Floating point math and functions (`scanf()`, `printf()`, etc.)
+
+The plain `libc.a`, which your software would be linked against by default, does not contain any floating point support code. This means, for example, that `printf("%f",...)` will not produce the desired output and that `scanf("%f",...)` may not read any data at all. If your program needs functions such as these or `atod()` then you must link against `libm.a` or the equivalent.
+
+To link the floating point support code with your software, use the `-lm` compiler option. 
+**Careful!** The order in which you specify the libraries to link against is important here. Thus, `gcc -o test test.c -lm -lc` would correctly link the program `test` against the proper floating point math library, but `gcc -o test test.c -lc -lm` would not.
+
+### The thread-safe library
+
+Thread-safety does not imply that you can have multiple callers access and close the same file. There is no resource tracking to that degree yet. All that the thread-safety tries to afford you is not to get into big trouble if simultaneous and overlapping accesses to files, memory allocation and other resources are taking place.
+
+The library code is supposed to be thread-safe if built with the `__THREAD_SAFE` preprocessor symbol defined. Note that 'thread-safe' does **not** mean 'reentrant'. Multiple callers for certain library functions are permitted, but not for all of them. For example, `mkdtemp()` is not thread-safe, and neither is `rand()` or `localtime()`. But as per *POSIX 1003.1c-1995* there are thread-safe variants of `rand()` and `localtime()` called `rand_r()`, `localtime_r()`, and others.
+
+The use of the socket I/O functions is problematic because the underlying `bsdsocket.library` API is not supposed to be used by any process other than the one which opened it. While one TCP/IP stack (my own "Roadshow") allows you to share the library base among different processes, if so configured, it is the exception. No other TCP/IP stack available for the Amiga robustly supports a similar feature. If the TCP/IP stack supports this feature, then the global variable `__can_share_socket_library_base` will be set to a non-zero value.
+
+Errors reported by the socket I/O functions which modify the global variables `errno` and `h_errno` may be directed to call the `__set_errno()` and `__set_h_errno()` functions instead, if the TCP/IP stack supports this feature. The global variable `__thread_safe_errno_h_errno` will be set to a non-zero value if it does.
+
+A much more serious problem resides with the `exit()`, `abort()`, `assert()` and `raise()` functions, and how the `SIGINT` signal is processed. In the thread-safe library only the `main()` function may directly or indirectly call the `exit()` function. No child process may do so, since this would wreck its stack context, crashing it instantly; the main program would be very likely to crash, too, because `exit()` will clean up after all memory allocations and files currently in use. Functions such as `abort()` and `raise()` may call the `exit()` function indirectly. And the `raise()` function may be invoked as part of the `Control+C` checking. You should make sure that the signal handling does not affect any child processes. This can be done by replacing the `__check_abort()` function or by disabling `SIGINT` processing altogether, such as through a `signal(SIGINT,SIG_IGN)` call.
+
+Also take care with file I/O involving the `stdin`/`stdout`/`stderr` streams; read/write operations on these streams will be mapped to the `Input()`/`Output()`/`ErrorOutput()` file handles of the process performing these operations. Since only this small set of operations is mapped, functions such as `fcntl()` or `select()` will not work on the `stdin`/`stdout`/`stderr` streams and the corresponding file descriptors `STDIN_FILENO`/`STDOUT_FILENO`/`STDERR_FILENO`. It is therefore strongly recommended to use the thread-safe library only for applications which can cope with the limitations described above.
+
+### Using gmon (PowerPC only)
+
+To use profiling, two steps are required. First of all, your program must be compiled with the *GCC* command line option `-pg`. This instructs the compiler to generate special profiling code in the prologue and epilogue of each function. Additionally, the program must be linked against `libprofile.a`. To do this, either manually add `-lprofile` to the linker command line, or modify the specs file as follows. Find the lines that look like this (it may actually differ slightly from your specs file, but the important thing is that the line before the line to be modified reads `lib:`):
+
+```
+lib:
+--start-group -lc --end-group
+```
+
+You will have to modify this to look like this:
+
+```
+lib:
+%{pg: -lprofile} --start-group -lc --end-group
+```
+
+Normally, the `specs` file is located at the compiler's installation directory. For cross-compilers, this is `/usr/local/amiga/lib/gcc/ppc-amigaos/*compiler-version*/specs`. For a native compiler, it's in `gcc:lib/gcc/ppc-amigaos/*compiler-version*/specs`. Most likely, your compiler will already have this added to it's `specs` file.
+
+Profiling makes use of a special PowerPC facility called the *Performance Monitor*. It allows to "mark" tasks and count only during while a marked task is running. This allows performance analysis to be made independent of the actual system load. The *Performance Monitor* is available on all PowerPC models supported by AmigaOS 4 except for the *603e*, and embedded versions of the PowerPC like the *405* and *440* series. Consult the manual of the appropriate chip for more information.
+
+### Implementation defined behaviour
+
+#### 'C' language
+
+##### Environment
+
+The `main(int argc,char **argv);` function may be called with an `argc` value of 0, in which case the `argv` variable will contain a pointer to the Amiga Workbench startup message, which is of type `struct WBStartup *`, and is defined in the Amiga system header file `<workbench/startup.h>`.
+
+##### Characters
+
+The current locale is derived from the current Amiga operating system locale settings. The `setlocale("")` function call will choose the current Amiga operating system locale settings. Any other name passed to the `setlocale()` function, with the exception of `"C"`, which selects the 'C' locale, must be a locale name, as used by the Amiga operating system function `OpenLocale()` in `locale.library`.
+
+##### Floating-point
+
+The 68k version of *clib2* supports single and double precision floating point numbers, according to the *IEEE 754* standard. The software floating point number support is built upon the Amiga operating system libraries `mathieeesingbas.library`, `mathieeedoubbas.library` and `mathieeedoubtrans.library`. The hardware floating point number support uses the M68881/M68882/M68040/M68060 floating point unit instead.
+
+The PowerPC version of *clib2* supports only double precision floating point numbers, according to the *IEEE 754* standard, because that is exactly what the PowerPC CPU supports. Single precision numbers may be implicitly converted to double precision numbers. This also means that the *C99* data type `long double` is identical to the `double` data type. Because there is no difference between these two, the library omits support for *C99* functions specifically designed to operate on `long double` data types, such as `rintl()`.
+
+Both the 68k and the PowerPC versions of *clib2* may call software floating point support routines in order to perform double and single precision operations that go beyond simple addition and multiplication, such as `sqrt()`. These functions come from Sun Microsystems <a href="http://www.netlib.org/fdlibm/">fdlibm 5.3</a> library.
+
+Unless your software is linked against `libm.a` no floating point functions will be available to it, possibly causing a linker error. When using the GNU 'C' compiler, you will want to add the option `-lm -lc` to the linker command line.
+
+The exception handling is currently entirely out of control of the developer and solely subject to the rules imposed by the operating system itself.
+
+The `fmod()` function returns the value of the `x` parameter and sets `errno` to `EDOM` if the `y` parameter value is 0.
+
+#### Library functions
+
+##### `NULL`
+
+The `NULL` pointer constant is defined in the `<stddef.h>` header and will expand to `((void *)0L)` if the 'C' compiler is used. For a C++ compiler the constant will expand to `0L` instead.
+
+##### `assert()` diagnostic messages
+
+The diagnostic messages printed by the `assert()` function take the following form:
+
+> `[*program name*] *file*:*line*: failed assertion "*condition*".`
+
+where:
+
+Label | Meaning
+----- | -------
+program name | Optional program name; if the program name is not yet known, then the entire text enclosed in square brackets will be omitted.
+file | The value of the `__FILE__` symbol at the location of the `assert()` call.
+line | The value of the `__LINE__` symbol at the location of the `assert()` call.
+condition | The condition passed to the `assert()` function.
+
+If available, the diagnostic messages will be sent to `stderr`.
+
+If the program was launched from Workbench or if the global variable `__no_standard_io` is set to a non-zero value, then the assertion failure message will not be displayed in the shell window, but in a requester window. The diagnostic message shown in this window will take the following form:
+
+> `Assertion of condition "*condition*" failed in file "*file*", line *line*.`
+
+The name of the program, if it is know at that time, will be displayed in the requester window title.
+
+##### Signal handling
+
+Only the minimum of required signals are supported by this library. These are `SIGABRT`, `SIGFPE`, `SIGILL`, `SIGINT`, `SIGSEGV` and `SIGTERM`.
+
+As of this writing `SIGFPE` is never called by the floating point library functions.
+
+The `Ctrl+C` event is translated into `SIGINT`. Signal delivery may be delayed until a library function which polls for the signal examines it. This means, for example, that a runaway program caught in an infinite loop cannot be aborted by sending it a `Ctrl+C` event unless special code is added which tests for the presence of the signal and calls the `__check_abort()` function on its own accord.
+
+Processing of the `Ctrl+C` event involves the internal `__check_abort()` function which polls for the presence of the event and which will call `raise(SIGINT);`. The `__check_abort()` function may be replaced by user code.
+
+##### Files
+
+No new line characters are written unless specifically requested.
+
+Space characters in a text stream before a new line character are read in and are not discarded.
+
+When data is read from a file, the last character does not have to be a new line character.
+
+No `NUL` byte will be appended to data written to a binary stream.
+
+There is no difference between text and binary streams.
+
+Writing to a text or binary stream does not truncate the associated file. A stream may be truncated by the initial `fopen()` call if the `mode` parameter starts with the letter `w`.
+
+The file position indicator is initially set to the end of an append mode stream.
+
+##### `printf()` family
+
+The `%p` conversion is the hexadecimal representation of the pointer, and it is preceded by the string `0x`.
+
+The `%a`, `%e`, `%f`, `%g`, `%A`, `%E`, `%F` and `%G` specifiers will produce the string `inf` for infinity.
+
+##### `scanf()` family
+
+The input for the `%p` conversion must be a hexadecimal number, preceded by either the string `0x` or `0X`.
+
+In the `%[` conversion a `-` (dash) character that is neither the first nor the last character in the scanset indicates that a subrange of characters should be used. Thus `%[a-d]` is equivalent to `%[abcd]`.
+
+The period (.) is the decimal-point character. The locale specific decimal-point character is accepted as an alternative to the period (.).
+
+##### `malloc()`, `realloc()` and `calloc()`
+
+In the standard `libc.a` implementation any request to allocate 0 (zero) bytes will fail. A result value of `NULL` will be returned and the global `errno` variable will be set to `EINVAL`.
+
+In the `libunix.a` implementation a request to allocate 0 (zero) bytes will result in an allocation of at least 4 bytes, which will be set to zero. Each zero length allocation will return a different memory address.
+
+##### `rename()`
+
+In the standard `libc.a` implementation the `rename()` function will fail if there already is a file or directory by the new name to be used.
+
+In the `libunix.a` implementation the `rename()` function will delete any existing file or directory by the new name.
+
+##### `remove()`
+
+In the standard `libc.a` implementation the `remove()` function will fail if the file is protected by deletion or currently in use.
+
+In the `libunix.a` implementation the `remove()` function will remove the file when the program exits or the file is closed.
+
+##### `abort()`
+
+The `abort()` function will flush all buffered files, close all the files currently open and delete temporary files.
+
+##### `exit()` and `_Exit()`
+
+The value passed to the `exit()` function will be passed to the Amiga operating system. The value of `EXIT_FAILURE` is equivalent to `RETURN_FAIL` as defined in the Amiga system header file `<dos/dos.h>`; this value maps to the number 20. The value of `EXIT_SUCCESS` is equivalent to `RETURN_OK` as defined in the Amiga system header file `<dos/dos.h>`; this value maps to the number 0.
+
+The `_Exit()` function will flush all buffered files, close all the files currently open and delete temporary files.
+
+##### `getenv()`
+
+Environment data is retrieved from the global Amiga operating system environment storage area through the `dos.library/GetEnv()` function. Global variables are stored in files in the `ENV:` directory.
+
+##### `system()`
+
+If the `command` parameter is not NULL and the `system()` function returns, then the result will be equivalent to the exit code of the program invoked, or -1 if the program could not be started. This follows the behaviour of the Amiga operating system function `dos.library/System()`. A return value of 0 typically indicates successful execution and a value > 0  typically indicates failure.
+
+##### Time
+
+The default time zone is derived from the Amiga operating system locale settings and takes the form `GMT+*hh*` or `GMT-*hh*`, respectively, in which *hh* stands for the difference between the local time zone and Greenwich Mean Time (actually, this is not GMT but UTC).
+
+The `clock_t` and `time_t` types are unsigned 32 bit integers. The `time_t` epoch starts with midnight January 1st, 1970.
+
+Daylight savings time is not supported.
+
+The reference point used by the `clock()` function is the time when the program was started.
+
+#### Locale specific behaviour
+
+The direction of printing is from left to right.
+
+The period (.) is the decimal-point character.
+
+The `strftime()` behaviour follows the Amiga operating system locale settings. If the 'C' locale is in effect, then the output generated by the `%Z` takes the form `GMT+*hh*` or `GMT-*hh*`, respectively, in which *hh* stands for the difference between the local time zone and Greenwich Mean Time (this is really UTC).
+
+## Conventions and design issues
+
+You will have noticed the 330+ files in this directory. This is not the best way to organize a runtime library, but at least all the bits and pieces are in plain sight. Each file stands for the one or two routines it contains. The name indicates what routine(s) that might be. Each file name is prefixed by the name of the header file in which the corresponding routine is defined. So, for example, you will find that `unistd_lchown.c` contains the definition of the `lchown()` routine, which has its prototype defined in the `<unistd.h>` header file.
+
+Internal function and variables which need to be visible across several modules have names prefixed with two underscores, as in `__stdio_init()`.
+
+By default all library routines follow the ISO 'C' conventions in that where implementation defined behaviour is permitted, the AmigaOS rules are followed. For example, `unlink()` will by default operate like `DeleteFile()` and `rename()` will return with an error code set if the name of the file/directory to be renamed would collide with an existing directory entry.
+
+
+## The startup code
+
+There are three program startup files provided. The most simplistic is in `startup.c` which I use for *SAS/C*. It just invokes the setup routine which eventually calls `main()` and drops straight into `exit()`.
+
+The `ncrt0.S` file was adapted from the *libnix* startup code which sets up the base relative data area, if necessary (the `SMALL_DATA` preprocessor symbol must be defined).
+
+The `nrcrt0.S` file was adapted from *libnix* startup code, too, and sets up the base relative data area for programs to be made resident. Note that the `geta4()` stub is missing here; it wouldn't work in a resident program anyway.
+
+The `ncrt0.S` and `nrcrt0.S` files are considerably smaller and less complex than the *libnix* code they are based on. This is because in this library design all the more complex tasks are performed in the `stdlib_main.c` file rather than in assembly language.
+
+
+## Documentation
+
+Well, you're reading it. There isn't anything much yet. You can consult the book *'C' - A reference manual* and you could look at the
+<a href="http://www.opengroup.org/onlinepubs/007904975">Open Group's Single Unix
+Specification</a>.
+
+It is recommended to browse the contents of the `include` directory. The header files contain information on library behaviour and not just data type and function prototype definitions. Specifically, the `<dos.h>` header file contains documentation about special libraries and global variables which may be used or replaced by user code.
+
+
+## Legal status
+
+Because this library is in part based upon free software it would be uncourteous not to make it free software itself. The BSD license would probably be appropriate here.

+<h3>5.3 Using gmon (PowerPC only)</h3>
 
+<p>To use profiling, two steps are required. First of all, your program must be compiled with
+the gcc command line option <tt>-pg</tt>. This instructs the compiler to generate special
+profiling code in the prologue and epilogue of each function. Additionally, the program
+must be linked with <tt>libprofile.a</tt>. To do this, either manually add
+<tt>-lprofile</tt> to the linker command line, or modify the specs file as follows.
+Find the lines that look like this (it may actually differ silghtily from your specs file,
+but the important thing is that the line before the line to be modified reads <tt>lib:</tt>):
+<pre>
+lib:
+--start-group -lc --end-group
+</pre>
+You will have to modify this to look like this:
+<pre>
+lib:
+%{pg: -lprofile} --start-group -lc --end-group
+</pre>
+<p>Normally, the specs file is located at the compilers installation directory. For cross-compilers,
+this is <tt>/usr/local/amiga/lib/gcc/ppc-amigaos/<i>compiler-version</i>/specs</tt>. For a native compiler,
+it's in <tt>gcc:lib/gcc/ppc-amigaos/<i>compiler-version</i>/specs</tt>. Most likely, your compiler will already have this added to it's specs file.</p>
+
+<p>Profiling makes use of a special PowerPC facility called the Performance Monitor. It
+allows to "mark" tasks and count only during while a marked task is running. This allows
+performance analysis to be made independant of the actual system load. The Performace Monitor
+is available on all PowerPC models supported by AmigaOS 4 except for the <tt>603e</tt>, and

+<h3>5.4 Implementation defined behaviour</h3>
+
+<h4>5.4.1. 'C' language</h4>
+
+<h5>5.4.1.1. Environment</h5>
+
+<p>The <tt>main(int argc,char **argv);</tt> function may be called with an <tt>argc</tt> value of 0,
+in which case the <tt>argv</tt> variable will contain a pointer to the Amiga Workbench startup
+message, which is of type <tt>struct WBStartup *</tt>, and is defined in the Amiga system header
+file <tt>&lt;workbench/startup.h&gt;</tt>.</p>
+
+<h5>5.4.1.2. Characters</h5>
+
+<p>The current locale is derived from the current Amiga operating system locale settings. The
+<tt>setlocale("")</tt> function call will choose the current Amiga operating system locale settings.
+Any other name passed to the <tt>setlocale()</tt> function, with the exception of <tt>"C"</tt>,
+which selects the 'C' locale, must be a locale name, as used by the Amiga operating system
+function <tt>OpenLocale()</tt> in <tt>locale.library</tt>.</p>
+
+<h5>5.4.1.3. Floating-point</h5>
+
+<p>The 68k version of clib2 supports single and double precision floating point numbers,
+according to the <i>IEEE 754</i> standard. The software floating point number support is built upon the Amiga
+operating system libraries <tt>mathieeesingbas.library</tt>, <tt>mathieeedoubbas.library</tt>
+and <tt>mathieeedoubtrans.library</tt>. The hardware floating point number support uses
+the M68881/M68882/M68040/M68060 floating point unit intead.</p>
+
+<p>The PowerPC version of clib2 supports only double precision floating point numbers, according to
+the <i>IEEE 754</i> standard, because that is exactly what the PowerPC CPU supports. Single precision
+numbers may be implicitly converted to double precision numbers. This also means that the <i>C99</i>
+data type <tt>long double</tt> is identical to the <tt>double</tt> data type. Because there is no
+difference between these two, the library omits support for <i>C99</i> functions specifically designed
+to operate on <tt>long double</tt> data types, such as <tt>rintl()</tt>.</p>
+
+<p>Both the 68k and the PowerPC versions of clib2 may call software floating point support
+routines in order to perform double and single precision operations that go beyond
+simple addition and multiplication, such as <tt>sqrt()</tt>. These functions come from
+Sun Microsystems <i>fdlibm 5.3</i> library.</p>
+
+<p>Unless your software is linked against <tt>libm.a</tt> no floating point functions will
+be available to it, possibly causing a linker error. When using the GNU 'C' compiler, you will
+want to add the option <tt>-lm -lc</tt> to the linker command line.</p>
+
+<p>The exception handling is currently entirely out of control of the developer
+and solely subject to the rules imposed by the operating system itself.</p>
+
+<p>The <tt>fmod()</tt> function returns the value of the <tt>x</tt> parameter and
+sets <tt>errno</tt> to <tt>EDOM</tt> if the <tt>y</tt> parameter value is 0.</p>
+
+<h4>5.4.2. Library functions</h4>
+
+<h5>5.4.2.1. <tt>NULL</tt></h5>
+
+<p>The <tt>NULL</tt> pointer constant is defined in the <tt>&lt;stddef.h&gt;</tt> header and
+will expand to <tt>((void *)0L)</tt> if the 'C' compiler is used. For a C++ compiler the constant
+will expand to <tt>0L</tt> instead.</p>
+
+<h5>5.4.2.2. <tt>assert()</tt> diagnostic messages</h5>
+
+<p>The diagnostic messages printed by the <tt>assert()</tt> function take the following form:</p>
+
+<blockquote><tt>[<i>program name</i>] <i>file</i>:<i>line</i>: failed assertion "<i>condition</i>".</tt></blockquote>
+

+<p>If the program was launched from Workbench or if the global variable <tt>__no_standard_io</tt> is set
+to a non-zero value, then the assertion failure message will not be displayed in the shell window, but
+in a requester window. The diagnostic message shown in this window will take the following form:</p>
+
+<blockquote><tt>Assertion of condition "<i>condition</i>" failed in file "<i>file</i>", line <i>line</i>.</tt></blockquote>
+
+<p>The name of the program, if it is know at that time, will be displayed in the requester window title.</p>
+
+<h5>5.4.2.3. Signal handling</h5>
+
+<p>Only the minimum of required signals are supported by this library. These are <tt>SIGABRT</tt>, <tt>SIGFPE</tt>,
+<tt>SIGILL</tt>, <tt>SIGINT</tt>, <tt>SIGSEGV</tt> and <tt>SIGTERM</tt>.</p>
+
+<p>As of this writing <tt>SIGFPE</tt> is never called by the floating point library functions.</p>
+
+<p>The <tt>Ctrl+C</tt> event is translated into <tt>SIGINT</tt>. Signal delivery may be delayed
+until a library function which polls for the signal examines it. This means, for example, that
+a runaway program caught in an infinite loop cannot be aborted by sending it a <tt>Ctrl+C</tt> event unless special code
+is added which tests for the presence of the signal and calls the <tt>__check_abort()</tt> all on its own.</p>
+
+<p>Processing of the <tt>Ctrl+C</tt> event involves the internal <tt>__check_abort()</tt> function which
+polls for the presence of the event and which will call <tt>raise(SIGINT);</tt>. The <tt>__check_abort()</tt>
+function may be replaced by user code.</p>
+
+<h5>5.4.2.4. Files</h5>
+
+<p>No new line characters are written unless specifically requested.</p>
+
+<p>Space characters in a text stream before a new line character are read in and not discarded.</p>
+
+<p>When data is read from a file, the last character does not have to be a new line character.</p>
+
+<p>No NUL byte will be appended to data written to a binary stream.</p>
+
+<p>There is no difference between text and binary streams.</p>
+
+<p>Writing to a text or binary stream does not truncate the associated file. A stream may be
+truncated by the initial <tt>fopen()</tt> call if the <tt>mode</tt> parameter starts with
+the letter <tt>w</tt>.</p>
+
+<p>The file position indicator is initially set to the end of an append mode stream.</p>
+
+<h5>5.4.2.5. <tt>printf()</tt> family</h5>
+
+<p>The <tt>%p</tt> conversion is the hexadecimal representation of the pointer, and
+it is preceded by the string <tt>0x</tt>.</p>
+
+<p>The <tt>%a</tt>, <tt>%e</tt>, <tt>%f</tt>, <tt>%g</tt>, <tt>%A</tt>,
+<tt>%E</tt>, <tt>%F</tt> and <tt>%G</tt> specifiers will produce the string <tt>inf</tt>
+for infinity.</p>
+
+<h5>5.4.2.6. <tt>scanf()</tt> family</h5>
+
+<p>The input for the <tt>%p</tt> conversion must be a hexadecimal number,
+preceded by either the string <tt>0x</tt> or <tt>0X</tt>.</p>
+
+<p>In the <tt>%[</tt> conversion a <tt>-</tt> (dash) character that is neither the
+first nor the last character in the scanset indicates that a subrange of
+characters should be used. Thus <tt>%[a-d]</tt> is equivalent to <tt>%[abcd]</tt>.</p>
+
+<p>The period (.) is the decimal-point character. The locale specific decimal-point
+character is accepted as an alternative to the period (.).</p>
+
+<h5>5.4.2.7. <tt>malloc()</tt>, <tt>realloc()</tt> and <tt>calloc()</tt></h5>
+
+<p>In the standard <tt>libc.a</tt> implementation any request to allocate
+0 (zero) bytes will fail. A result value of <tt>NULL</tt> will be returned and
+the global <tt>errno</tt> variable will be set to <tt>EINVAL</tt>.</p>
+
+<p>In the <tt>libunix.a</tt> implementation a request to allocate
+0 (zero) bytes will result in an allocation of at least 4 bytes, which will
+be set to zero. Each zero length allocation will return a different
+memory address.</p>
+
+<h5>5.4.2.8. <tt>rename()</tt></h5>
+
+<p>In the standard <tt>libc.a</tt> implementation the <tt>rename()</tt> function
+will fail if there already is a file or directory by the new name to be used.</p>
+
+<p>In the <tt>libunix.a</tt> implementation the <tt>rename()</tt> function will
+delete any existing file or directory by the new name.</p>
+
+<h5>5.4.2.9. <tt>remove()</tt></h5>
+
+<p>In the standard <tt>libc.a</tt> implementation the <tt>remove()</tt> function
+will fail if the file is protected by deletion or currently in use.</p>
+
+<p>In the <tt>libunix.a</tt> implementation the <tt>remove()</tt> function
+will remove the file when the program exits or the file is closed.</p>
+
+<h5>5.4.2.10. <tt>abort()</tt></h5>
+
+<p>The <tt>abort()</tt> function will flush all buffered files,
+close all the files currently open and delete temporary files.</p>
+
+<h5>5.4.2.11. <tt>exit()</tt> and <tt>_Exit()</tt></h5>
+
+<p>The value passed to the <tt>exit()</tt> function will be passed to the
+Amiga operating system. The value of <tt>EXIT_FAILURE</tt> is equivalent
+to <tt>RETURN_FAIL</tt> as defined in the Amiga system header file
+<tt>&lt;dos/dos.h&gt;</tt>; this value maps to the number 20. The value
+of <tt>EXIT_SUCCESS</tt> is equivalent to <tt>RETURN_OK</tt> as defined in
+the Amiga system header file <tt>&lt;dos/dos.h&gt;</tt>; this value maps to
+the number 0.</p>
+
+<p>The <tt>_Exit()</tt> function will flush all buffered files,
+close all the files currently open and delete temporary files.</p>
+
+<h5>5.4.2.12. <tt>getenv()</tt></h5>
+
+<p>Environment data is retrieved from the global Amiga operating system environment
+storage area through the <tt>dos.library/GetEnv()</tt> function. Global variables are
+stored in files in the <tt>ENV:</tt> directory.</p>
+
+<h5>5.4.2.13. <tt>system()</tt></h5>
+
+<p>If the <tt>command</tt> parameter is not NULL and the <tt>system()</tt> function returns, then the result will
+be equivalent to the exit code of the program invoked, or -1 if the program could not be started.
+This follows the behaviour of the Amiga operating system function <tt>dos.library/System()</tt>.
+A return value of 0 typically indicates successful execution and a value &gt; 0 
+typically indicates failure.</p>
+
+<h5>5.4.2.14. Time</h5>
+
+<p>The default time zone is derived from the Amiga operating system locale
+settings and takes the form <tt>GMT+<i>hh</i></tt> or <tt>GMT-<i>hh</i></tt>,
+respectively, in which <i>hh</i> stands for the difference between the local
+time zone and Greenwich Mean Time.</p>
+
+<p>The <tt>clock_t</tt> and <tt>time_t</tt> types are unsigned 32 bit integers.
+The <tt>time_t</tt> epoch starts with midnight January 1st, 1970.</p>
+
+<p>Daylight savings time is not supported.</p>
+
+<p>The reference point used by the <tt>clock()</tt> function is the time
+when the program was started.</p>
+
+<h4>5.4.3. Locale specific behaviour</h4>
+
+<p>The direction of printing is from left to right.</p>
+
+<p>The period (.) is the decimal-point character.</p>
+
+<p>The <tt>strftime()</tt> behaviour follows the Amiga operating system locale
+settings. If the 'C' locale is in effect, then the output generated by the
+<tt>%Z</tt> takes the form <tt>GMT+<i>hh</i></tt> or <tt>GMT-<i>hh</i></tt>,
+respectively, in which <i>hh</i> stands for the difference between the local
+time zone and Greenwich Mean Time.</p>

+
+- Unused slabs which get recycled are no longer reinitialized from
+  scratch if their chunk size matches what the allocator needed.
+  If the chunk size matches, the list of available chunks is
+  left unchanged, and just the various counters are reset.
+
+- Added __get_slab_stats() function.
+
+- Added support for global __slab_purge_threshold tuning variable.
+
+
+c.lib 1.211 (23.11.2016)
+
+- Added more consistency checking to the slab allocator, which is
+  built if DEBUG is defined in "stdlib_slab.c".
+
+- Memory allocations are no longer guaranteed to be aligned to
+  64 bit word boundaries. In fact, this has not even worked
+  reliably in the past 10 years.
+
+- Memory allocation request sizes are now rounded to multiples of
+  32 bit words (the size of an address pointer) instead to the
+  size of a 64 bit word.
+
+- Reduced the memory footprint of the memory allocation management
+  data structures by reusing the most significant bit of the
+  memory allocation size. This allows many more allocations to fit
+  into the 32 byte chunk slabs, but limits the maximum memory
+  allocation size to a little less than 2 GBytes.
+
+- Added integer overflow checks to the memory management code.
+
+- Reduced the memory management overhead further. This cuts an
+  additional 8 bytes per allocation, unless neither the slab
+  allocator nor memory pools are available. With this reduction
+  the slab allocator is able to use 16 byte chunks, which cover
+  memory allocation requests of 1..8 bytes.
+
+- Fixed a bug caused by returning an allocation back to a slab
+  which passed the wrong pointer.
+
+
+c.lib 1.210 (22.11.2016)
+
+- Added __get_slab_allocations() function which will report information
+  about each memory allocation made by the slab allocator which does
+  not come from a slab.
+
+- If the first slab in the list of slabs which share the same chunk
+  size has no more room, it means that all other slabs following
+  it have no room either. This speeds up the test to find a slab with
+  free space, which can now abort and directly proceed to allocate
+  memory for a new slab.
+
+- If an empty slab's decay count hits zero, it is moved to the front
+  of the empty slab list to be reclaimed more quickly.
+
+- Allocations made from the slab now carry a pointer back to the
+  slab which they are a part of. This speeds up deallocation but
+  has the downside of making the smallest usable slab chunk size
+  64 bytes, which is double what used to be the minimum before.
+
+
+c.lib 1.209 (21.11.2016)
+
+- The maximum slab size is now 2^17 bytes (= 131072). If you request
+  a slab size larger than this, you will get slab sizes of 131072
+  bytes instead.
+
+- Enabling the memory management debugging code no longer produces
+  compiler errors.
+
+
+c.lib 1.208 (19.11.2016)
+
+- Updated <stdlib.h> with new functions and data structures for
+  use with the slab allocator.
+
+- Added __get_slab_usage() function which can be used to query
+  the slab allocator memory usage at runtime.
+
+
+c.lib 1.207 (18.11.2016)
+
+- Added a slab allocator which replaces the use of memory pools or the
+  plain AllocMem() operations, respectively. In order to activate the
+  slab allocator, choose a slab size (e.g. 2048 bytes or 4096 bytes)
+  and declare a global variable like this:
+
+     ULONG __slab_max_size = 2048;
+
+  Memory allocations smaller than the slab size will be made from
+  "slabs", i.e. large chunks of memory of the given size. Larger
+  allocations will be managed separately.
+
+
+m.lib 1.206 (24.4.2015)
+
+- The fscanf() family failed to parse and convert %f parameters correctly
+  if the respective number did not begin with a digit, but a decimal
+  point. Hence ".7" would not be processed, but "0.7" would.
+
+c.lib 1.206 (24.4.2015)
+
+- Reworked the __putc() and putc() macros to reference the 'c' input
+  parameter only once, and to be free of side-effects when tinkering
+  with the buffer position.
+
+- isatty() had the __fd_lock() call in the wrong place, which could have
+  led to cleanup problems later.
+
+- The close action in the stdio, socket and termios hook code now
+  also zaps the fd pointer itself after cleaning up the file descriptor
+  table entry.
+
+- Removed the remains of all the stack extension and stack overflow/underflow
+  checking code. It never actually worked. The bit that does work is the stack
+  usage measurement code, plus the bit that sets up the the custom stack
+  according to local setting or by calling a query function.
+
+
+c.lib 1.205 (21.8.2010)
+
+- Added dlclose(), dlerror(), dlopen() and dlsym() functions, which are
+  available only under OS4. There is a variant of dlopen() in libunix.a
+  which will perform a path name conversion. Note that these functions
+  will not work in the thread-safe variant of the library because it
+  would be unwise to tinker with the currently running program's binary.
+
+- Added support for ELF shared objects and libraries. This is implemented through
+  constructor/destructor functions, which means that you can use this
+  functionality even in Amiga Exec style shared libraries, with the proper
+  library initialization code to invoke the constructor/destructor functions
+  for you.
+
+- Updated uname() to recognize AmigaOS 4.1.
+
+- The translation from Unix to Amiga path names did not properly process
+  multiple occurences of "/./" in the path name. Thanks go to Steven Solie
+  for finding the issue.
+
+- The detection of "/./" and "/../" patterns in Unix path names to be
+  translated into Amiga path names did not test if it was overrunning
+  the end of the string.
+
+- If strcmp(), strncmp() and memcmp() detect a pair of different
+  characters, then the function result must be calculated as if the
+  characters were of type "unsigned char". This is a requirement
+  according to the ISO 'C' (1994) standard. Thanks go to Georg Steger
+  for finding the issue.
+
+- The definitions for INT_MIN, INT_MAX and UINT_MAX in <limits.h> no
+  longer use long integer types, as prompted by Steven Solie.
+
+
+c.lib 1.204 (11.11.2008)
+
+- The memory allocated by malloc() and friends is now of type MEMF_PRIVATE
+  under OS4 and beyond. The AmigaOS 2.x/3.x compatible code will still
+  use MEMF_ANY in the same situation, though. Other uses of MEMF_ANY have
+  been replaced as well where MEMF_PRIVATE would have made better sense.
+
+- I/O buffers allocated are now aligned according to the CPU cache line size,
+  if the operating system can supply such detailed information.
+
+- unsetenv() now returns a status value.
+
+- Corrected the function prototype for wcspbrk().
+
+- Added function prototypes for mbrtowc_l(), wcscoll_l(), wcscspn() and wcsrchr().
+
+
+c.lib 1.203 (28.4.2008)
+
+- Added 68k stubs to amiga_rexxvars.c for the OS4 build to use. The new code now
+  works just about exactly like the amiga.lib RVI code used to do, which means
+  that there is no artificial length limit for the number of characters a string
+  retrieved may have, and the code is largely reentrant.
+
+- To work around a bug in the Roadshow TCP/IP stack (since fixed), the waitselect()
+  function now substitutes a 10 microsecond timeout for a zero length timeout.
+
+- isatty() no longer crashes if passed a socket rather than a file.
+
+- Rewrote the GetRexxVar()/SetRexxVar() functions (mostly) in 'C', using available
+  code as a reference. The 68k stubs currently only work for the 68k version of
+  the library, and a solution for the OS4 build still needs to be found. The code
+  is currently untested, but it should be complete.
+
+- The printf() family now ignores argument specifications, as in "%2$d %1$d",
+  which are used for localization on some platforms. This is a non-standard
+  feature and the way clib2 treats it for now is just intended to avoid
+  trouble while performing the conversion.
+
+- [tboeckel]: when compiling amiga_rexxvars.c for m68k/OS3 the GetRexxVarFromMsg()
+  and SetRexxVarFromMsg() can no longer cause linkage errors if the header files
+  predate the SDK for OS 3.5.
+
+- [jlangner]: the log() and log10() functions always returned -inf() even if the
+  arguments was within the valid range for a log() function. Using DBL_EPSILON as
+  the threshold was not correct as EPSILON is 2.2204460492503131E-16 whereas
+  values like 1E-200 are still valid double values for a log().
+
+
+c.lib 1.202 (16.1.2007)
+
+- Added llrint() function contributed by Henning Nielsen Lund. Thank you
+  very much!
+
+- <unistd.h> now also include <stdio.h>, so that the SEEK_SET, etc. macros
+  are defined for lseek() to use.
+
+- Added a wrapper function which handles the thread-safe stdio stream
+  resolution.
+
+- In tcflush() a break signal can no longer cause the read flush loop
+  to be quit with two semaphores still locked.
+
+- In __obtain_daemon_message() the test to verify if the bsdsocket.library API
+  would support the server API functionality checked the wrong feature. Fixed.
+
+- Switched over the fd->fd_DefaultFile references to fd->fd_Socket where
+  sockets are used rather than file handles.
+
+- Added functions which modify the callback function and the userdata pointer
+  stored in a low level unbuffered file/socket data structure. These function
+  perform the proper locking and are thus safe to use in a thread-safe environment.
+
+- The low level unbuffered file/socket now has a public equivalent, which
+  is defined (along with the typedefs and flags) in <sys/clib2_io.h>. Functions
+  for tinkering with it are still to come.
+
+- The math kernel code no longer uses its own private scalbn() function.
+
+- Added a function prototype for the _exit() function. Note that _exit() is
+  not an ISO 'C' function.
+
+- Corrected the getopt() function prototype, as prompted by Henning Nielsen Lund.
+
+- The printf() family no longer adds a 0 or 0x prefix if the alternate
+  conversion modifier is present for the %o and %x conversions and the
+  value to be converted is 0 already. Put another way, printf("%#x %#o",0,0);
+  now prints "0 0". This required another change so that %p always includes
+  the 0x prefix even if the pointer involved is a NULL pointer.
+
+- readlink() no longer sort-of-works for files and directories. It now only
+  works for soft linked objects and returns an error for everything else.
+  This is based upon a fix by Peter Bengtsson. Thank you very much!
+
+- Moved the lstat() local Lock() function into its own separate file.
+
+- uname() now returns correct and robust information for OS version
+  numbers > 36. This integrates a fix by Peter Bengtsson. Thank you
+  very much!
+
+- Moved the crtbegin.o/crtend.o files out of the link libraries. Moving
+  them in was intended to work as a fix for the shared library build, but
+  now it seems that this has to be done at the link stage through the
+  GCC specs file...
+
+- Integrated a fix for __rem_pio2() which affects sin(), tan() and cos(),
+  contributed by Steven Solie. Thank you very much!
+
+- The internal 'struct fd' file descriptor table entry data structure
+  now has a user data field entry.
+
+- Rearranged the contents of the 'struct fd' file descriptor table entry
+  data structure in preparation for making it public. Also added a version
+  field so that user code can handle changes to it gracefully. The default
+  file is no longer a BCPL pointer to a file handle by default, but
+  both a BPTR and a socket identifier, wrapped into a union.
+
+- Added experimental tilde expansion in Unix path names. This still needs
+  some more work.
+
+- __get_default_file() called __fd_unlock() without having called
+  __fd_lock() first. Ouch.
+
+- Removed an unnecessary pair of __fd_lock()..__fd_unlock() calls from
+  ttyname_r().
+
+- The libunix.a unlink() function is now reentrant, or at least thread-safe.
+
+- You can now make unlink() stop after a failed deletion attempt which
+  failed because the object to be deleted was reported as being "in use".
+  The libunix.a variant defaults to report the deletion to have succeeded
+  under these circumstances and later tries to delete the files marked
+  for deletion. See <dos.h> for a brief documentation of how to change
+  the behaviour.
+
+- basename() and dirname() can no longer return NULL. They truncate the
+  resulting path name instead. This is done so because some code that
+  calls basename() or dirname() does not check if the function's return
+  value is NULL.
+
+- The SetOwner() fall-back code for Kickstart 2.04 was passing the wrong
+  parameters to the file system. The first (dp_Arg1) should have been
+  zero. Ouch.
+
+- basename() is not supposed to modify the string it is passed and should
+  return a pointer to a string which can be modified. Now it does. Same
+  thing for dirname().
+
+- asctime_r() now returns NULL if the buffer is too short to hold even a single
+  byte of data.
+
+- ttyname() now calls ttyname_r(). Also, the libunix.a version of ttyname_r()
+  will produce "/CONSOLE" rather than "CONSOLE:".
+
+
+c.lib 1.201 (21.9.2006)
+
+- If defined, the local environment variable "DISABLE_COMMANDLINE_WILDCARD_EXPANSION"
+  will disable expansion of wildcard patterns passed on the command line.
+  Note that if the variable is not set then the global variable
+  '__expand_wildcard_args' will provide the defaults for the switch that
+  controls whether the wildcard expansion takes place. And after the
+  environment variable has been checked, the '__expand_wildcard_args_check'
+  function pointer can still be used to override the switch.
+
+- fstat() now works with "NIL:" and "/dev/null", respectively. Not that
+  it returns much useful information, though.
+
+- The _PC_MAX_INPUT query for file handles now returns the default
+  buffer size.
+
+- Integrated the new OS4 build makefile collection, as contributed by
+  Steven Solie. Thank you very much!
+
+- Added the missing strerror_r() function.
+
+- fpathconf() should work with the stdio streams, even in the thread-safe
+  library version, again.
+
+- Updated m68k specs file in /documentation to contain an own __CLIB2__
+  define so that existing m68k compilers also have this define. In addition,
+  the common "-noixemul" option can now also be specified but will do a NOP
+  so that Makefiles sharing multiple runtime lib setups work without
+  a warning.
+
+- Added a new callback function which can be used in programs which want
+  to avoid that the command line wildcard expansion takes place.  
+
+- __get_default_file() now dynamically fills in file handles for the
+  stdin/stdout/stderr streams if it's part of the thread-safe library.
+
+- fpathconf() now checks if the file descriptor is really referring to a file.
+
+- The termios hook entry code could file descriptor's embedded file handle
+  rather than what the thread safe library had dynamically bound to the
+  stdin/stdout/stderr streams.
+
+- execve() now finds commands in the current directory again, even if you
+  omit the leading "./" path name.
+
+- The execve() code that looks for the command/script file now begins by
+  checking if the file name includes path separators. If it does not,
+  then the search for the command begins with the resident command list;
+  otherwise the local directories are checked. The new code also properly
+  cleans up after itself (a FreeDeviceProc() was missing) and the "PROGDIR:"
+  lock now always refers to the directory in which the command/script
+  file is found.
+
+- Added the missing fdim() and fdimf() functions to the build
+  makefiles. The OS4 build makefile was missing lrint() and
+  lrintf(). Ouch.
+
+- Added the POSIX exec() family functions, based upon code contributed
+  by Henning Nielsen Lund. Thank you very much!
+
+- atoll() no longer sets 'errno' directly but now calls __set_errno()
+  instead.
+
+- Added pathconf(), fpathconf(), sysinfo(), ftime(), ulimit(), getrlimit()
+  and setrlimit() as contributed by Peter Bengtsson. Thank you very much!
+
+- Added the missing S_ISSOCKET() macro to <sys/stat.h>. Note that this
+  is not actually a POSIX feature.
+
+- Added fmin(), fminf(), fmax() and fmaxf() to the build makefiles.
+  Somehow I must have forgotten about them :-(
+
+- select() and waitselect() can now be called without any file descriptor
+  sets to work with, as some software does which uses select() in place
+  of sleep().
+
+- The <sys/ioctl.h> header file now includes both <sys/select.h> and
+  <sys/filio.h> for better compatibility with the TCP/IP stack header
+  files.
+
+- Added the global variable __expand_wildcard_args which can be used
+  to disable wildcard pattern expansion of command line parameters when
+  linked against "libunix.a". Note that this has no effect on the "regular"
+  libc.a behaviour.
+
+
+c.lib 1.200 (17.4.2006)
+
+- The default break signal mask (SIGBREAKF_CTRL_C) is no longer
+  hard-coded. You can override it at link time with a different
+  variable value for __break_signal_mask. This may have to be
+  augmented by an API for changing the value.
+
+- Added a waitselect() function which works very much like the
+  bsdsocket.library/WaitSelect() function.
+
+- Added <sys/time.h> include to <sys/socket.h> due to latest "TimeVal" change
+  in the OS4 SDK. Otherwise "struct timeval" will not be defined at the time
+  the <net/if.h> of the netincludes will be included by <proto/bsdsocket.h>.
+
+- The strftime() hook function had the locale and character parameters
+  switched, which made 'setlocale(LC_ALL,""); strftime(..);' unusable.
+  Fixed.
+
+- fchown() and chown() now accept owner and group ID values of -1, which
+  indicate that the respective information should not be changed.
+
+- The OS4 library build now includes the crtbegin.o and crtend.o object
+  files in the libc.a library, which solves a problem with the thread-safe
+  shared library support code.
+
+
+c.lib 1.199 (6.3.2006)
+
+- In <stdio.h> MAXPATHLEN is now equivalent to PATH_MAX (from <limits.h>),
+  as suggested by Henning Nielsen Lund.
+
+- Added lockf() support, as supplied by Henning Nielsen Lund.
+  Thank you very much!
+
+- symlink() now also works for absolute and relative links, and is
+  part of "libunix.a". This patch was supplied by Henning Nielsen Lund.
+  Thank you very much!
+
+- The __main() stub function expected by the 68k GCC build is no
+  longer part of "stdlib_main.c". This helps the C++ support, since the
+  __main symbol definition no longer clashes with the definition in
+  "libgcc.a".
+
+- The printf() family stripped trailing zeroes from the integer part
+  of %g output. Fixed.
+
+- Moved an allocation size roundup operation in realloc().
+
+
+c.lib 1.198 (11.12.2005)
+
+- Added <fenv.h> for C99, and the (yet unimplemented) functions
+  feclearexcept(), fegetenv(), fegetexceptflag(), fegetround(),
+  feholdexcept(), feraiseexcept(), fesetenv(), fesetexceptflag(),
+  fetestexcept(), fetestround() and feupdateenv().
+
+- Replaced the old pow() implementation. However, powf() may need to
+  be changed to set a domain error.
+
+- In libunix.a malloc(), calloc() and realloc() no longer treat a
+  request to allocate 0 bytes as an error, returning NULL. They all
+  return a pointer sized memory chunk (= four bytes) initialized to
+  NULL (= 0) instead.
+
+- The alloca() implementation which allocates memory from the system
+  rather than the local stack frame is thread-safe now. It also
+  interacts with the realloc(), calloc(), free() and malloc() functions
+  in that the alloca() cleanup routine is called once alloca() has
+  done its job. If all the memory allocated through alloca() has been
+  released no further calls to the cleanup function will be made.
+
+- In the thread-safe library, realloc() permitted two different overlapping
+  calls to succeed in trying to reallocate the same chunk of memory due to
+  a race condition. Fixed.
+
+- Added a new function __get_mem_stats() (the prototype is in <dos.h>) which
+  can be used to query the current and maximum memory usage, counting the
+  allocations performed through malloc(), free() and all other functions which
+  use them.
+
+- Added another function called __reset_max_mem_stats() which will reset the
+  counters for "maximum amount of memory used" and "maximum number of chunks
+  allocated" to the current figures for these values.
+
+- Fixed the alloca() declaration in <stdlib.h> so that software which keys
+  off the fact whether or not the alloca preprocessor symbol is defined
+  will do the right thing.
+
+- Added an optional call-back function which can be called if alloca()
+  is about to return NULL, which some software does not consider.
+  Rather than letting such software drop into an illegal memory access
+  or worse, that call-back function will be invoked instead, which can
+  print an error message and eventually call abort().
+
+
+c.lib 1.197 (4.11.2005)
+
+- Updated math_hypot.c to a newer (e_hypot.c 1.3 95/01/18) version from
+  fdlibm which uses macros for manipulating the high and low words of a
+  double, like the rest of fdlibm functions in clib2. The previous version
+  would give bogus results when compiled with -O3 in clib2 which lead to
+  "interesting" results (and lots of fun while searching for the problem)
+  in Ghostscript. Wish I managed to track this down yesterday for 1.196
+  release... <aantonijevic>
+
+- Implemented atanh() and atanhf() which were not listed in the TODO
+  file but were still unimplemented up until now.
+
+- Replaced ldexp() and modf().
+
+- Added __set_h_errno() and __get_h_errno() functions.
+
+- The thread-safe library now tries to enable bsdsocket.library base
+  sharing and attempts to make the TCP/IP stack call the local
+  __set_errno() and __set_h_errno(), so that any Process calling
+  the library functions will get a chance to see proper error
+  codes. Whether any of these features could be enabled can be tested
+  through two global variables __can_share_socket_library_base and
+  __thread_safe_errno_h_errno which are defined in <dos.h>. Note that
+  for both features to work you will need the Roadshow bsdsocket.library
+  version 4.275 or higher.
+
+- In <stdbool.h> the preprocessor definition should read
+  "__bool_true_false_are_defined" rather than "__bool_true_and_false_are_defined".
+  Thanks go to Peter Bengtsson for finding and fixing it.
+
+- The network startup code no longer checks for the presence of a possible
+  daemon startup message by default. You now have to enable this feature
+  by declaring a global variable called "__check_daemon_startup" which is
+  described in <dos.h>.
+
+- Moved the code which rebinds the standard I/O streams to the server
+  socket into a separate function which can be overridden by user code.
+
+- Updated the new __obtain_daemon_message() function to call a
+  bsdsocket.library API function to determine if what appears to be
+  a valid daemon startup message is sound.
+
+- Replaced the OS4 specific build makefile with an updated version
+  prepared by Steven Solie. Thank you very much!
+
+
+c.lib 1.196 (11.10.2005)
+
+- Removed the various workarounds associated with <unistd.h>, required
+  for building code that references the networking API. It is now possible,
+  provided you build your code with an existing TCP/IP API header file
+  set (such as from the "Roadshow" SDK) without running into data type
+  or function prototype declaration conflicts. I have added local versions
+  of <arpa/inet.h>, <netinet/in.h>, <netdb.h>, <sys/filio.h>, <sys/ioccom.h>,
+  <sys/ioctl.h>, <sys/select.h> and <sys/socket.h> and updated <unistd.h>,
+  <pwd.h> and <grp.h> accordingly. Note that some of the function prototypes
+  will conflict with the bsdsocket.library/usergroup.library API, which is
+  why you can disable the declarations through the __NO_NET_API preprocessor
+  symbol: if defined, none of the function prototypes will be defined.
+
+- Implemented lrintf(), lrint(), lroundf(), lround(), nearbyintf(),
+  nearbyint(), remquof(), remquo(), roundf(), round(), tgammaf(),
+  tgamma(), truncf(), trunc(). Sort of implemented fmaf() and fma(),
+  which really ought to be done in "SIMD" fashion.
+
+  This completes the "real" floating point math library (ignoring
+  for a moment that the floating point environment code is still
+  not implemented).
+
+- accept() now calls the bsdsocket.library accept() function first
+  and then hooks up the socket with the clib2 data structures. This
+  makes it possible to have several Processes calling the accept()
+  stub at the same time.
+
+- When the main() function returns directly or indirectly by way of
+  calling exit(), the IoErr() value set at this time will now be
+  preserved until the program really returns control to the shell.
+  This turned out to be easier to implement than I had originally
+  thought, thanks to the fact that the atexit() functions are all
+  invoked straight after the exit() call.
+
+- strtoimax(), strtoumax(), strtod(), strtof(), strtol(), strtoll(),
+  strtoul() and strtoull() now count how many digits were converted.
+  If that number is zero, then the conversion is considered to have
+  failed: 0 is returned and the 'ptr' parameter reference is initialized
+  with a pointer to the string to be converted. This has two consequences:
+
+     1) A floating point number that has no digits in the significand
+        is no longer converted to zero. For example ".e10" can no longer
+        result in a successful conversion.
+
+     2) You can detect if a conversion is successful by comparing pointers
+        after the conversion function has returned:
+
+           char * str;
+           char * ptr;
+           long n;
+
+           n = strtol(str,&ptr,10);
+           if(n == 0 && str == ptr)
+              printf("conversion has failed");
+
+- Following detection of a stack overflow, the startup code eventually
+  called _exit(). It should have called exit() instead.
+
+- tmpnam() wrote more than L_tmpnam bytes to the name buffer. Also, the
+  TMP_MAX value was off by one.
+
+
+c.lib 1.195 (3.9.2005)
+
+- In __time_delay() the CheckIO() test was wrong and should have
+  tested for a request still in progress. Fixed.
+
+- Modified select() to support plain files, too. The new code now
+  compares the current file position against the current file size,
+  if that file is on a file system, or simply checks if there is
+  any data in the file (which works for the default PIPE: device).
+
+- The raw file descriptor structure member fd_Position is now
+  always updated, regardless of whether the file supports random
+  access or not.
+
+- The wildcard escape character used in __wildcard_expand_init() was
+  wrong. It should have been "'" but it was "`". Fixed.
+
+- The startup code now references the linker symbol generated for
+  the user-supplied main() function.
+
+- log(+/-0), logb(+/-0), log10(+/-0) now return -infinity.
+
+- getcwd() now considers a buffer size of 0 an error, and it sets
+  the errno code to ERANGE if the buffer is too small.
+
+- With Unix path semantics enabled, rename() now fails if either
+  the old or the new name are empty strings. Same thing for
+  opendir(), utime(), unlink(), chown(), link(), readlink(),
+  realpath(), chdir(), access(), stat(), rmdir(), lstat(),
+  chmod(), statfs() and open()/fopen().
+
+- Fixed several issues with the formatted output of strftime()
+  for the "C" locale: "%p" could return " PM", "%c" is now
+  equivalent to "%a %b %e %T %Y", "%x" is equivalent to "%m/%d/%y"
+  and "%X" is now equivalent to "%T".
+
+- The 68020/030/040/060 versions of the library now include the
+  64 bit integer conversion code. The plain 68000 version does not.
+
+- The 64 bit integer conversion code used in by the scanf() family
+  was broken due to a misplaced overflow check, which had the cruel
+  effect of triggering for 32 bit integers as well. Fixed.
+
+- DoTimer() did not allocate the local MsgPort correctly. Fixed.
+
+
+c.lib 1.194 (15.7.2005)
+
+- Added getopt_long to libunix.a <tfrieden>
+
+- Added new libprofile.a which implements gprof gmon.out output <tfrieden>
+
+- Added the function profil() to libc.a <tfrieden>
+
+- Added ftello() and fseeko() which both merely call the equivalent (at
+  least for clib2) ftell() and fseek() functions, respectively.
+
+- statfs() never stated that a disk was mounted for read-only access
+  because the wrong InfoData structure member was tested. Fixed.
+
+- lstat would overwrite the name parameter via ReadLink(..., name, ...)
+  instead of ReadLink(..., new_name, ...) <tfrieden>
+
+- Implemented exp2()/exp2f() and log2()/log2f() as suggested by
+  Henning Nielsen Lund. Thank you very much!
+
+- The pattern matching code which expands command line arguments, as part
+  of libunix.a, now translates the "*" wildcard into "#?" unless you prefix
+  it with a backtick ("'"), which is the wildcard pattern escape character
+  used on AmigaOS.
+
+- Repaired the pattern matching code which expands command line arguments:
+  it no longer requires that any parameters are quoted and it is automatically
+  enabled if you link against libunix.a, without libc.a standing a chance to
+  accidentally override it.
+
+- Fixed a bug in vfprintf that would surface when the buffer was enlarged
+  if the pattern was too large to fit the static internal buffer <tfrieden>
+
+- Added file system names to statfs <tfrieden>
+
+- Moved all the constructor code out of "stdlib_init_exit.c" and into the
+  files which initialize global data, such as the new "stdlib_program_name.c"
+  and "stdlib_malloc.c".
+
+- Until I can find a way to invoke it from within the library, the
+  __machine_test() function is no longer invoked.
+
+- Tagged global data with NOCOMMON attributes.
+
+- Added the __lib_init() and __lib_exit() functions, which are part of the
+  thread-safe library and which can be used to hook up clib2 with standard
+  Amiga shared library/device code. Some documentation on how to use them
+  can be found in the <dos.h> header file.
+
+- Added a complete shared library skeleton example to demonstrate how the
+  clib2 shared library initialization/cleanup functions should be used.
+  This is a dual-build library which will both work with the plain 68k
+  AmigaOS and the PowerPC native AmigaOS4. The example source code can be
+  found in the "skeleton_library" subdirectory.
+
+- The thread-safe version of isatty() should now work for stdio
+  file descriptors, too.
+
+- Retrofitted thread-safety into the termios code.
+
+- The socket/usergroup API function and data type definitions that used to
+  be defined in <unistd.h> have been moved into a separate header file
+  <sys/clib2_net.h> which, for backwards compatibility, can be include
+  from within <unistd.h> if the preprocessor symbol __USE_CLIB2_NETLIB
+  is defined early on. Eventually, <sys/clib2_net.h> should be removed
+  from the general header files and become a local library build header
+  file altogether. Note that in this case you would have to build your
+  own software using common TCP/IP SDK header files.
+
+- <sys/types.h> now also includes <time.h> and <stddef.h>.
