are now defined as empty macros unless __THREAD_SAFE is defined.

Both the library and the user code need to be rebuilt with the
preprocessor symbol __THREAD_SAFE defined to get thread-safe
code.

and ftrylockfile().
- Modified the internal FILE structure to allow for thread locking.
Note that this again requires that the library is rebuilt!
- Added or modified macros for getc_unlocked(), getchar_unlocked(),
putc_unlocked() and putchar_unlocked().
- Added rand_r().
- Added flockfile()/funlockfile() wrappers around all stdio
functions.

parameters (which is by default linked in with libunix.a),
regular expressions can no longer prompt dos.library requesters
to appear. However, to be on the safe side, if you are expecting
to pass regular expressions on the command line, do not use
the wildcard expansion code such as by overriding the library
symbols with dummy functions such as are used in the file
"stdlib_wildcard_expand.c".
- Added a new variable '__open_locale' which can be used to
restrict all library functions to use the "C" language locale
rather than the current system locale settings. In addition
to that, two new functions __locale_exit() and __locale_init()
can be used to close and (re-)open the system locale at a
later time.
- Local ("static") functions are now identified by the STATIC
qualifier. This was done in preparation for changes that will
deal with global and local data and the issue of thread safety.

code which initialized them.
- Reading/changing the errno variable is no longer done directly, but
involves accessor functions.
- References to the HUGE_VAL quantity now involve an accessor function, too.
- Changed the manner in which the __huge_val constant is initialized by
the __math_init() function.

"long long" data type are no longer prototyped if the library is built
for SAS/C.

compiler settings, which can either default to an unsigned or
signed definition.
- Changed the rules again for the use of stderr/stdout redirection when
printing error messages. It is always safe to redirect them now and
no requester will appear unless you specifically set the value of the
"__no_standard_io" variable to TRUE in your program.

messages and assertion failure notifications as requesters. The exception
is in redirecting stderr to NIL: which will prompt the requester use.
- gettimeofday() now calls GetSysTime() rather than DateStamp() to obtain
the current system time. This resolves granularity issues since the
DateStamp() result was only accurate by 1/50 of a second.
- The "ptrdiff_t" definition in <stddef.h> now defaults to type 'int' rather
than 'long int'.

to the built-in function.
- Updated the stdio.h, stdlib.h, string.h and unistd.h header files
to declare function prototypes for the __MEM_DEBUG versions of the
library functions only if that preprocessor symbol is defined.
- If a SIGINT signal is caught and processed by the default signal
handler, the localized "*** BREAK" string will be printed rather
than the built-in one.

be part of amiga.lib. While comparable functionality is available
in rexxsyslib.library V45, the new stubs might be helpful during
porting. Care must be taken since these functions don't work
exactly like the originals.
- Integrated strlcpy() and strlcat() which are intended to be safer
replacements for strncpy() and strncat().
- The program's task priority is now configurable through an external
variable '__priority'.
- The process name to be used when detaching can be configured through
the new '__process_name' variable.
- The minimum required operating system version can be configured
through the new '__minimum_os_lib_version' variable; a matching
error message can be provided through the new '__minimum_os_lib_error'
variable.
- The default console window specification can be overriden through
the new '__stdio_window_specification' variable.
- The socket initialization code did not set up a reference to the
'h_errno' variable correctly. This had the effect of making name
and address resolution errors trash the 'errno' variable instead
and leaving 'h_errno' always set to 0. Fixed.

- Moved the locale initialization/cleanup code into constructors
and destructors.
- The socket cleanup function is now a destructor.
- The math cleanup function is now a destructor.
- The wildcard cleanup function is now a destructor.
- The stdio cleanup function is now a destructor.
- The stack extension cleanup function is now a destructor.
- The code that cleans up after the program's current directory
was changed is now a destructor function.
- Moved the initialization/cleanup code for unlink() into constructors
and destructors.
- Moved the initialization/cleanup code for usergroup.library into
constructors and destructors.
- Added usleep(), and created wrapper code that both sleep() and
usleep() can use.
- Added strtoll() and strtoull(), with further changes to <limits.h>
and <stdlib.h>.

- <stdarg.h> now tries to use the compiler supplied, machine specific
<stdarg.h> file and also includes the OS4-specifc <sys/amigaos-va.h>
file, if necessary.
- Added another test to <sys/time.h> to check if the "timeval" definition is
already in place. If it is, <exec/types.h> will not be included.
- <sys/time.h> can be made to define the timeval data structure locally if
the __USE_CLIB2_TIMEVAL preprocessor symbol is defined. In this case no
<exec/types.h> or <devices/timer.h> file will be read.
- The sprintf() family did not properly handle empty strings as format
specifications. This would result in a necessary buffer flush action
getting skipped, which consequently did not put the string termination
character into the output buffer.

- The <assert.h> header file was missing the C++ 'extern "C" { .. }'
declarations.
- Added a new function __get_default_file() which allows direct access
to the low level file handle/socket descriptor associated with a
file descriptor.

- Added "math_hypot.c"
- The 68k build makefile now builds the vfprintf/vfscanf functions
with %lld/%llu support.
- Split the release notes file into changes and actual release notes,
which may overlap but differ in technical content.

- Updated code and header files to state exactly which ISO 'C' version
is meant by the "The following is not part of the ISO 'C' standard."

- Integrated rint() and rintf().

- Added h_strerror() function to libnet.a; there's a global 'h_errno'
variable available, too.
- <signal.h> now defines a type 'sig_t'.
- <unistd.h> now allows the 'fd_set' type to be referenced as
'struct fd_set', too.
