SYSTEM_DEVEL_PREFIX says: "This defaults to $(DEVEL_PREFIX)/usr", but it
actually defaults to just "($DEVEL_PREFIX)".
Just thought I'd mention it... :)

I found math fpclassify function is broken because FP_XXX definitions
in libm/fp_private.h is incompatible with include/math.h.
Also I noticed fp_private.h and fpmacros.c use many 'long int' for
32bit variables. I think these should be int or u_int32_t.
Here is a patch against 0.9.20.
fp_private.c:
--- fix union members (use u_int32_t instead of 'unsigned long int').
--- remove incompatible FP_XXX definitions (and some unused macros).
fpmacros.c:
--- use FP_NAN instead of FP_QNAN/FP_SNAN.
--- use correct type (int instead of long int).
--- fix union members (use u_int32_t instead of 'unsigned long int').
--- remove unnecessary cast.
Note that I had to remove weak_alias for isnanl,isinfl to compile
patched fpmacroc.c. Is this really needed? Original behavior (using
isnan for isnanl) seems problematic anyway.

Attached is a patch for a bug I found in libc/termios/ttyname.c.
Essentially the length of the buffer is calculated incorrectly in a
strncpy call and then the null terminator is placed on the byte after
the buffer.
This probably cause some very strange behavior on my system (it ended up
setting malloc's heapsize to zero) but may be innocuous on other systems.

checking for duplicates and returning an alias if an existing lib
is already loaded is still correct for the dlopen case.

debug versions of uClibc with -O0, but libpthread/linuxthreads/spinlock.c
will not compile without at least -O1 optimization...

Hack a fix for ctype support of 8-bit codeset locales.
Note: toupper/tolower mappings do not handle the special cases for the
tr_TR and az_AZ locales, since the wide versions currently handle them
either. That will be addressed when I rewrite the data generation tools
and the libc locale code.

(2) Add a command-line option --uclibc-cc with the same functionality.

I hate to add this stuff, but it is specified by SuSv3...

Move stub gettext functions to a stub libintl to make switching in
gnu gettext easier. Also add a few gnu-isms.
Change to using hidden names with global weak aliases for the extended
locale functions, as expected by libstd++.
Slightly rework the locale data generation stuff to allow pregenerated
locale data to be used with buildroot.

I found that current pread/pwrite is broken on mips.
On mips, kernel needs 6 arguments for pread/pwrite system call. (3
words for first 3 arguments + 1 padding word + 2 words for last 64bit
argument). Also, mips64 kernel needs just 4 arguments so no wrapper
will be required.
This is a patch against 0.9.20.

With this, the shared lib loader works on mips once again.

a chain of dependent libraries or libraries that depend on other
shared libraries will not work!
So with a well placed
dyn_chain->flags |= RTLD_GLOBAL;
everything is now working perfectly!!! Sweet!!!!
This patch also removes some leftover junk from my previous efforts.

libraries multiple times, wasting memory and causing different libraries to use
different symbol sets, some of which were not properly resolved.
Continue scrubbing ld.so and converting it to use proper types.
