secure_getenv

add alloc_size attribute to reallocarray

  add getentropy, lazy arc4random clone (OpenBSD)

add reallocarray as defined by OpenBSD
to ease implementation, turn uintmax_t into uint128_t on 64-bit platforms

Massive ARM changes from Enrico Scholz

fix compiler warnings
make i386 start code slightly smaller (I think profiling was broken,
too, and this should fix it)
add PIC stack smash handler

make gnu grep compile

add wcstombs and wcsrtombs

add mblen

  add btowc, wctype, iswctype

  add mbsinit, mbrlen, mbtowc, wctomb, mbrtowc, wcrtomb

  fix fd leak in if_nameindex (Florian Westphal)
  fix printf %g (well, get closer)

  update syscalls
  lots of fixes from Markus FX Oberhumer:
    * better signal handling error detection
    * setjmp.S on i386
    * getenv on i386
    * sys/stat.h -malign-double fix
    * update fcntl.h for MIPS to 2.6.13 version
    * jmp_buf is 40*8 instead of 58*8 on ppc64.
    * This patch fixes the section of the TOC entries on ppc64
    * libstdc++ updates for gcc 4
    * remove cstddef and cwchar (no longer needed)
    * int -> ssize_t for read and write
    * sigjmp.c: __mask_was_saved was not set in all cases!
    * another round of ILP64 cleanups

add clearenv for udev

add div,ldiv,lldiv

  remove throw() statements for functions taking function pointer
    arguments (qsort, besearch, ftw)

  Lots of fixes and patches from Markus Oberhumer.
    libstdc++ compatibility
    ilp64 compatibility
    make diet libc compile with -Werror on 13 platforms
  ppc64 now compiles again

- adding 'getgrouplist'
- fixing type of 'unsetenv'
- adding missing realtime syscalls 'clock_*' 'timer_*' and types

C99 fixes and a new printf test suite (Enrico Scholz)

  first throw, then attributes (Andreas Jabs)

make headers C++ compatible

  add __attribute_dontuse__ to declare a few functions as deprecated
  use above to flag a few BSDisms ;-)

  rename __pure__ to __pure (Laurent Bercot)

move alloca to <alloca.h>

#define MB_CUR_MAX for sed

add killpg prototype (Luc Van Oostenryck)
remove some compiler warnings (Luc Van Oostenryck)
better rand() from Knuth's TAOCP (Luc Van Oostenryck)

add strtold and strtof for tcc

lots of cleanups from Florian LaRoche

change __malloc__ to __attribute_malloc__

make rand.S use the RAND_MAX from stdlib

a few patches to make Berkeley DB and Postfix compile

add x86 getenv, grantpt, ptsname and unlockpt from Thomas Ogrisegg
add prototypes in stdlib.h.
remove large commented out code from gethostent
fix parser bug for "search foo,bar" in /etc/resolv.conf

start using __attribute__((malloc)) to improve tell the gcc 3 optimizer
that a function returns a malloced pointer, i.e. the pointer can't alias
any existing data.

__dtostr was really disgusting.
It still is, but it sucks in different ways now.
We really need to __dtostr, one for %g and one for %f.
The new version won't do scientific notation at all, but it's better
than the previous version anyway.

make headers more C++ compliant.

rand48 from Johannes Kloos

fix -ansi -pendantic errors and warnings about inline and long long.

removed "some" warnings ...

enabled a few more obscure gcc warnings and started adding fluff code to
silence them.

don't define EXIT_SUCCESS and EXIT_FAILURE twice in stdlib.h.  Thanks,
Tino Reichardt!

add mkdtemp

popen did not set close-on-exec flag on fd, could leak fd on malloc
error in fdopen, system did not ignore SIGCHLD and thus had a potential
wait() race.

#define alloca to __builtin_alloca with gcc.

found some missing prototypes...
and a BUG in getpropto*

add *abs.

add clock

add realpath and wrap getcwd (syscall returns length, not buf).

add setenv and execlp.

the alloca prototype was duplicate.

add alloca to stdlib.h and have diet include stdlib

kludged around a little with Jeff's entlib stuff ;-}

add div and a lot of prototypes.

various compilation fixes for the different platforms.

several stdio fixes courtesy to the S-Lang test suite.

implemented really crappy rand() and srand() (if you need real
randomness, use a real PRNG).  Implemented qsort() and bsearch().
For some reason, they outperform their glibc counterparts by a
surprisingly large margin _and_ are smaller.

define EXIT_SUCCESS and EXIT_FAILURE.

files where missing (?)
