Fork

Updates to the working apps list from Kagan Kongar. Thanks!

Apply integer overflow security fix for "CERT Advisory CA-2002-25 Integer
Overflow In XDR Library" http://www.cert.org/advisories/CA-2002-25.html
Patch from Solar Designer <solar@openwall.com>.

Message catalog support for internationalization is not currently
provided by uClibc, and here I have added macros to disable it.
-Erik

Per suggestion from Miles Bader, move calloc.c to libc/stdlib.
Also, Manuel notices that I forgot to check for when nmemb=0,
which would result in a segfault, so fix that case as well.
-Erik

When symbols are missing, its supposed to be an error...
-Erik

Several pthreads updates. Enable linuxthreads_db. Several fixes
related to thread local storage.
-Erik

Fixup the last missing pieces of thread locking
-Erik

Rework RPC code once again. By default, only enable the
stuff needed for NFS mounts, rsh, and similar.
-Erik

Enable getpt prototype.

Changed fflush() behavior to no-op for r/w streams in read-mode.
This falls under undefined behavior wrt ANSI/ISO C99, but
SUSv3 seems to treat it as a no-op and it occurs in some apps.
Fixed a problem with _stdio_fwrite() not checking for underlying
write() failures.
Fixed both _stdio_fwrite() and _stdio_fread() to make sure that
the putc and getc macros were disabled if the stream was in
and error state.

The above changes should take care of a problem initially reported
by "Steven J. Hill" <sjhill@realitydiluted.com>.

Unify calloc (its the same thing regardless of the underlying
malloc implementation). Fix problem reported to bugtraq about
problems with integer overflow that can occur during the
computation of the memory region size by calloc (and similar
functions) which could result in a subsequent buffer overflow.
-Erik

Just in case, crash if somehow `exit' returns anyways
-Erik

remove BUILDTIME since it is not used

A couple of little cleanups I forgot to check in.

When DODEBUG and HAS_WCHAR were enabled and HAS_LOCALE was disabled,
wchar.c wouldn't compile:
wchar.c: In function `__mbsnrtowcs':
wchar.c:631: `__ctype_encoding_7_bit' undeclared (first use in this function)
This fixes it by keeping the locale specific asserts hidden when not relevant.
-Erik

Use MALLOC_REALLOC_MIN_FREE_SIZE.

(MALLOC_REALLOC_MIN_FREE_SIZE): New macro.
Enable debugging if MALLOC_DEBUGGING is defined.

(HEAP_MIN_SIZE): New macro.
(HEAP_MIN_FREE_AREA_SIZE): Increase size.
Enable debugging if HEAP_DEBUGGING is defined.

Joseph Chiu <josephc@idealab.com> found an off-by-one bug. oops!

In the allocate-and-copy case, don't include the malloc header in our
size calculations.

Sigh. A bit more cleanup.

Update debugging printfs.

Per discussion on the mailing list, simply vfork -> fork mapping to only apply
iff we do not have vfork available, which is simpler and more reasonable.
-Erik

More i960 support

Patch from Martin Proulx <mproulx@okiok.com> to fix i960
create_module() support.

Patch from Alexander Pevzner <pzz@pzz.msk.ru> to fixup things when invoked as
the C++ compiler to to automagically add include/g++ into the include search
path, and automagically add -lstdc++ and -lm into the set of automatically
linked libraries.

You fool foolish. Goodbye level 2.

Always build utils by default
-Erik

Account for MALLOC_HEADER_SIZE when calculating new size.

Use MALLOC_HEADER_SIZE.
