Fork

Several naming cleanups so threads work properly again

Fix a corner case which I had botched.

Add a better error msg

Per discussion with Manuel, when we call __stdio_flush_buffers
from abort() and from _exit(), we need to ensure that flushing
will not cause us to block. So use fcntl to set the fd's to
non-block mode...

Update todo list

Test for libcrypt (which is partly broken ATM)

This should be a little better...

I was confusing the effects of _LARGEFILE_SOURCE with those of
_FILE_OFFSET_BITS regarding aliasing of the *64 funcs. :-(
Hopefully, this version is correct...

Build fix for arm

Special rules for mipsel. Force some variables in Config, in
case they're wrong (they are.) Remove Config during clean.

Several mips fixes from Geoffrey Espin. With these, busybox with
ash/vi/etc now works just fine with uClibc on mips.

Let the large file stuff be cancelable

Update string tests per glibc 2.2.5's string tester. Looks like
our stpncpy is flunking...
-Erik

Oops. I forgot to commit this file...

When vfork is not available and we have an MMU, then use fork()
-Erik

Lose the _GNU_SOURCE and just add __USE_GNU to the one file that needs
it, since we definately do not want silent remapping of functions to
their large-file counterparts.
-Erik

Add ldexp to the !C99 list, since it is defined in POSIX as
being part of the classic math lib stuff.
-Erik

Miles Bader noticed that I'd messed up by always pulling
errno in, regardless of whether it is being used...
-Erik

Fix from John Rigby to fix stat() so it actually works.

oops. I had accidentally typed in "clean" when I meant "clone".
This fix makes pthreads actaully work on powerpc.
-Erik

This is a bit less messy

Enable thread support

Several needed cleanups to the gcc wrapper.
-Erik

Merge in the pthread library. This is the linuxthreads library taken from
glibc 2.1.3 and ported to work with uClibc by Stefan Soucek and Erik Andersen
(me). Stefan has hacked things up such that linuxthreads runs on MMU-less
systems (tested only on arm-nommu). Erik cleaned things up and made it work
properly as a shared library.
-Erik

Add a test from Stefan Soucek for pthread_cond_timedwait(). On
mmu-less ARM perhaps sigsetjmp() isn't working?

Output an error if uClibc's and app's largefile configuration are incompatible.

Doh! Miles Bader noticed a couple of spots where I forgot
to mark __stdio_flush_buffers with weak_function. Oops!

Rename __stdio_close_all to __stdio_flush_buffers. Eliminate an
unnecessary variable

Doh!

Miles Bader writes:
Programs that don't use stdio crash in the `exit' function, because
they call through the pointer__uClibc_cleanup, which has a value of 0.
It has a value of 0 because __uClibc_main.c initializes it to the
address of `__stdio_close_all', which is a weak symbol (and so is 0 if
stdio is not used).
This patch from Miles fixes it, though we need to audit
__stdio_close_all usage to be sure...
