2012-11-18nptl: fix gcc noreturn warningMike Frysinger
Current builds show the warning: CC libpthread/nptl/pthread_create.os libpthread/nptl/pthread_create.c: In function 'start_thread': libpthread/nptl/pthread_create.c:418:3: warning: function declared 'noreturn' has a 'return' statement [enabled by default] libpthread/nptl/pthread_create.c:418:3: warning: 'noreturn' function does return [enabled by default] Looking at glibc, it does not mark this function as noreturn. Testing code size, gcc is smart enough to detect the code never actually returns regardless of the attribute. So drop it to keep in sync with glibc and to avoid the warnings.

2012-08-29librt: re-add SIGCANCEL to the list of blocked signal in helper threadFilippo Arcidiacono
Indeed if the libpthread is before the libc in the library look up the SIGCANCEL is removed from the list of the blocked signal by sigfillset func, this can produce the handler not properly called.

2012-07-24Remove pragma weak for undeclared symbolBernd Schmidt
pthread_initialize is a static function and should not be mentioned in a header. The #pragma weak for it appears to confuse gcc-4.7. Signed-off-by: Bernd Schmidt <bernds@codesourcery.com

2012-06-15linuxthreads.old: cleanup a bitPeter S. Mazinger
Use __UCLIBC_HAS_TLS__ instead of USE___THREADS (although this LT implementation will never support TLS). Disable unused/unneeded members of the pthread_functions structure. No redirect/forward for _pthread_cleanup_push/pop, it would have not worked anyway due to the fact, that the structure member was not initialized. Disable it's possible internal use in libc-lock.h.

Keep only fork (and it's hidden variant) and __libc_fork. Common __libc_fork prototype in unistd.h.
