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.

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.

- 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:".

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.

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.

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.

exit but just returns to the caller without doing anything, execve()

- 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 :-(

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.
