A user application built with -D_POSIX_C_SOURCE=200112L and
#include signal.h, yields following compilation error:
------------------->8-----------------------------
arc-linux-uclibc-gcc -D_POSIX_C_SOURCE=200112L hello.c
In file included from
/opt/INSTALL/lib/gcc/arc-linux-uclibc/4.4.7/../../../../arc-linux-uclibc/sys-include/signal.h:429,

/opt/INSTALL/lib/gcc/arc-linux-uclibc/4.4.7/../../../../arc-linux-uclibc/sys-include/bits/pthreadtypes.h:48:
error: expected specifier-qualifier-list before 'size_t'
------------------->8-----------------------------
I can confirm that an ARM buildroot based toolchain, configured with
uClibc daily
snapshot (BR2_UCLIBC_VERSION_SNAPSHOT) + old pthreads suffers from same
problem.

----------------------->8---------------------------
The fix is to make sure size_t is explicitly provided to pthreadtype.h
