Default branch: MAIN

  implement malloc case for realpath
  use __builtin_mul_overflow in calloc if gcc is recent enough

support clang by adding -fno-integrated-as

add some crude shotgun debugging code to malloc, enabled by
WANT_FREE_OVERWRITE

  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

  use _FILE_OFFSET_BITS consistently (Indan Zupancic)

the regparm attribute in typedefinition generats error with gcc-2.95 on
non-x86 arch... (reported: Johannes Stezenbach)

ARGH!  gcc 3.4 breaks regparm attributes on i386!

make calloc weak (Martin Pohlack)

faster string routines, alloc fix (Thomas Ogrisegg)

sparc and unalignd access EQUALS to SIGBUS...

  remove =0 for static variables (Thomas Ogrisegg)

stddef.h: use gcc provided types.
alloc.c:  wrong prototype in internal declaration. (with gcc-types)
atexit.c: new needed symbol for new pthread-implementation.

prevent division by zero in calloc when nmemb is 0

more malloc fixes

more correct fix...

fix calloc integer overflow (notified by RUS-CERT)

remove warnings

optional malloc(0) returns a "zero"-object

fix typo in ARM unified syscall,
work around gcc 3 warnings caused by gcc internal wrong prototypes,
make malloc(0) return NULL again,
fix cfgetospeed (used wrong field of struct termios, oops!)

- parisc clone & atomic testandset
- modifications to libpthread to respect the UPgrowing stack of rarisc
  and inverse lock logic
- added compiler option to i386 (this saves 9 byte per C-function)

some types were int insteat of long (now less warnings on alpha).

implement if_nameindex with a test and if_freenameindex as alias for
free.

move regparm prototypes to the front (cosmetics)

fix Olaf's broken regparm attributes ;)

release the evil !
new alloc/free code

a few more cleanups and tcflow and tcsetattr have been optimized by
Frank Klemm.

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

SEGV in realloc ... missed to check if there is a free-block.

malloc uses PAGE_SIZE (better page-usage, less pain)

missed a line and had wrote the wrong .... (arg...)

"total" rewrite of malloc structure:
- realloc can resize
- blocks >128k are handled by mmu :)

even more clean-up

start getting rid of kernel headers.

a ton of warnings fixed ;)

lots of errno cleanups,
lots of errno related thread-safeness cleanups in librpc (don't ask).

WANT THREAD SAFE !

some minor changes...

changed some...
1. removed some pthread dependencies for dietlibc
2. added a pthread_sys_alloc to compensate

make alloc.c compile again if WANT_THREAD_SAVE is not set.

arg... removed deadlock...

minor pthread changes

initial hopefully thread save alloc/free.
bugfix in realloc

files where missing (?)
