[Samuel Thibault]

They are mostly shared with Linux

gcc/ada/ChangeLog:

	* s-oscons-tmplt.c [__GNU__] (_XOPEN_SOURCE, _BSD_SOURCE): Define.
	[__GNU__]: Include <pthread.h> and <signal.h>
	[__GNU__]: Set MSG_Forced_Flags to "MSG_NOSIGNAL".
	[__GNU__]: Define SIZEOF_sigset.
	[__GNU__]: Define PTHREAD_*SIZE
