Accomodate building under cygwin

grr. It's a void *, not a char *.

Change 'N' to '__size' to avoid conflicts with common #define of N

Sorry. Changed this while fixing the last bug and forgot to change it
back. Unfortunately, none of my test cases caught it.

Cope with autoconf's broken AC_FUNC_MALLOC macro, which redefines malloc as
rpl_malloc if it does not detect glibc style
returning-a-valid-pointer-for-malloc(0) behavior. This wrapper calls malloc()
as usual, but if N is zero, we allocate and return a 1-byte block instead....
sigh...

Fix (hopefully) scanf behavior for nul bytes in the stream when processing
%c, %s, and %[ specifiers. Note that scanf is undergoing rewrite so I
didn't bother optimizing this. I did run all my regression tests though.
Set EOF correctly for fmemopen on readonly streams. I really need to
check what glibc behavior is for the various open modes though.

Add in a default file for m68k.

Sleep was returning the wrong value because:

* nanosleep returns the remaining time, not the time slept

* nanosleep only fills out the remaining time if it returns -1 (ie., the
sleep was interrupted)

Fix from Paul Dale <pauli@snapgear.com>

(__libc_open): Fix wacky indentation.

setjmp was trashing r12 which is bad and can cause apps to crash if they are
using r12. r12 is supposed to be preserved across C function calls. r0-r7
are trashable :-)

Some small fixups for the h8 support and add the h8s platform support.

Fixup __libc_open to use varargs and match the prototype.

On the H8 varargs are rather unusual and if you declare a function with
varargs, it had better use them or it won't work.

uClibc 0.9.19 has a bug in globfree(). If the previous call to
glob(...,pglob) used the GLOB_DOOFFS flag to reserve the first
pglob->gl_offs slots of pglob->gl_pathv, globfree(pglob) would attempt
to free the objects pointed to by those slots. If those objects were not
on the heap, the system would crash.

The attached patch fixes this.

Comment on glibc's MALLOC_CHECK_ support.

Thierry De Corte notices that when UCLIBC_HAS_FLOAT is disabled, we must also
disable drand48, drand48_r, erand48, and erand48_r since they use floats.

Fix SIGTRAP handling on arm. The defination of struct ucontext,
which was copied from glibc, is wrong. So fix it.

Patch from Marshall M. Midden:

It turns out that uClibc's syslog.c does not close sockets when
doing retries and when it exits due to errors. This patch fixes
it.

Konrad Taro Eisele noticed the sparc struct stat was broken.
Fix it.

Patch from Liam Girdwood to fix mips profiling when using
newer gcc versions.

(free_to_heap): Unlock the heap before returning in the
__UCLIBC_UCLINUX_BROKEN_MUNMAP__ case. Fix from YYang1@Winbond.com.tw.

Avoid errors with buggy preprocessors

Oops. Don't call strip twice

resync with glibc 2.3

sjhill needs to buy donuts for everyone

Make it so debugging pthreads works, even with DODEBUG turned off
-Erik

Minor cleanup to better sync with glibc 2.3

Compliance with MIPS ABI and MIPS kernel changes.

Patch from Jordan Crouse to avoid potential rendering problems

remove a leftover debug printf

Patch from Stefan Allius

the ldd.c wasn't compilable for SuperH due to a missing ELFCLASSM define and
the readelf executable was linked with a wrong dynamic linker path. To fix
this I removed the --uclibc-use-build-dir.

The patch also fixed all the compiler warnings (-Wall -W).

Erik made a few additional changes to eliminate unused function arguments
and fixup a static variable that was was doing the wrong thing
