?S:	This variable conditionally defines the HAS_SIGVEC symbol, which indicates
?S:	that BSD reliable signals are supported.
?S:.
?S:d_sigvectr:
?S:	This variable conditionally defines the HAS_SIGVECTOR symbol, which
?S:	indicates that the sigvec() routine is called sigvector() instead, for
?S:	reasons known only to Hewlett-Packard.
?S:.
?S:d_sigintrp:
?S:	This variable conditionally defines the HAS_SIGINTRP symbol, which
?S:	indicates that the siginterrupt() routine is available.

?C:HAS_SIGVEC (SIGVEC):
?C:	This symbol, if defined, indicates that BSD reliable signals are
?C:	supported.
?C:.
?C:HAS_SIGVECTOR (SIGVECTOR):
?C:	This symbol, if defined, indicates that the sigvec() routine is called
?C:	sigvector() instead, and that sigspace() is provided instead of
?C:	sigstack().  This is probably only true for HP-UX.
?C:.
?C:HAS_SIGINTRP (SIGINTRP):
?C:	This symbol, if defined, indicates that the siginterrupt() routine
