freebsd-nq/include/pthread.h
David Schultz 48a3f7d9ae Fix the visibility of several prototypes. Also move pthread_kill() and 
pthread_sigmask() to signal.h. In principle, this shouldn't break anything,
since they're already in signal.h on other systems, and the FreeBSD
manpage says that both pthread.h and signal.h need to be included to
get these functions.

Add a hack to declare pthread_t in the P1003.1-2008 namespace
in signal.h.
