The 'struct tm' is now properly updated to reflect the time and date information which comes out of the number of seconds calculated.
A bug reported by Andreas Falkenhahn is resolved which had the effect of distorting the number of seconds calculated.
Added integer overflow test to calloc().
Tiny change in getopt_long() so that the value pointed to by the "longindex" parameter is always initialized to an invalid index position (that being -1), instead of 0. The value of 0 can break some shell commands, most notably GNU wget.
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.
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.
- Replaced ISO Latin 1 code #160 with a plain blank space (ASCII code #32) where necessary

- 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.

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.

GCC version, e.g. 4.0.4 or earlier.

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.

that there is no artificial length limit for the number of characters a string

- 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:".
