Roland McGrath Jan. 8, 2015, 10:29 p.m. UTC 
Fixes the build of libpthread.so on non-Linux.  
(Also some incidental sanity-checking with the #error.)
No effect on existing configurations.

Thanks,
Roland

	* nptl/pthread_sigmask.c [SIGCANCEL || SIGTIMER || SIGSETXID]: #error.
	(pthread_sigmask): Call sigprocmask, not __sigprocmask.
