the common "-noixemul" option can now also be specified but will do a NOP

- 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

stdin/stdout/stderr streams.

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 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 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.

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.

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().

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.

- 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.

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>

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.

nearbyint(), remquof(), remquo(), roundf(), round(), tgammaf(),
tgamma(), truncf(), trunc(). Sort of implemented fmaf() and fma(),

This completes the "real" floating point math library (ignoring
for a moment that the floating point environment code is still
not implemented).

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.

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.
