Fix pthreads to use the rt signals if present
-Erik

Begin efforts at reentrance by seperating out the stuff that isn't
reentrant and labeling it, and making everything else const.
-Erik

Don't use fixed buffers if we have an mmu such that malloc
and realloc are cheap.
-Erik

Silence warnings, clean things up.
-Erik

Cleanup the mess, remove now obsolete files
-Erik

Write a new strxfrm that doesn't make function calls. Uses the same logic as
before but unrolls the func calls and thereby eliminates some steps and some
bytes. Now adds just 40 bytes to .text.
-Erik

Yipe. As Joseph Chiu noticed, sockvec is supposed to be an int*
not an int.

Revert Erik's patch to vasprintf and fix the real issue.
The writer for the stream returned by open_memstream was supposed to
keep the buffer nul-terminated. I apparently left out a statement.

This patch from Rik Faith <faith@alephnull.com> fixes a potentially
non-NULL terminated string problem that could result from the use
of open_memstream(). Manuel may have a better solution, but this
one works for me, since with this plus the popen fix I can now run
things like gdb properly. Thanks Rik!

A patch from Ted Phelps to fix popen(). Ted writes:
There is a minor bug in the implementation of popen(). In the case
where the file descriptor returned from its call to pipe() is the same
as the file descriptor that it is meant to be (where the dup2() branch
is not taken), the end of the pipe is still closed by close(reading)
even though it shouldn't be.
Thanks Ted!

Kill the libc-lock headers, which we do not use and which are
not correct for uClibc. Fix setenv locking to behave itself.
-Erik

Oops. Forgot to check this in. Thanks Martin Volf for noticing
-Erik

Added a version of nl_langinfo for the stub C/POSIX locale support.

Fix up of '_dlopen' call and removal of unneeded argument in call '_dl_load_elf_shared_library'.

If we are cross-compiling, don't even try to build the target utilities.

Changes so that 'regdef.h' gets included in the development environment.

Moved to 'sys' directory.

Doh!

Patch from Robert Griebl <griebl@gmx.de> to support
getusershell() and friends.

Rework setenv, getenv and friends per the latest glibc code, but cleaned
up for readability. Merge in putenv. Add clearenv as a side effect.
-Erik

-#ifdef _POSIX_THREADS
+#ifdef __UCLIBC_HAS_THREADS__

Fixup totally broken locking code... No storage for the mutex,
wrong ifdef macro..
-Erik

Fix dependancy. again.

Fix dependancy for util target
-Erik

Doh! A silly typo broke select...
-Erik

And with this, the alpha port is not basically working.
-Erik

don't include the linux dir. Pointless and broken.
-Erik

Put GCCINCDIR here, which is the only place it is needed.
-Erik

Cool. An even better way to get the gcc include dir which eliminates
several external program calls, thanks to a suggestion from rmk.
-Erik

Make these properly cope with 64bit systems
-Erik
