fix error handling for pthread_sigmask it must return errno, not -1, and should reject invalud values for how. 2011-03-09 20:31:06 -05:00			`#include <signal.h>`

clean up pthread_sigmask/sigprocmask dependency order it's nicer for the function that doesn't use errno to be independent, and have the other one call it. saves some time and avoids clobbering errno. 2011-07-30 21:09:14 -04:00			`#include "syscall.h"`
