>Description:


It was a great surprise to me to find out that signal.h (or, in fact, sys/signal.h) doesn't contain definition of such a basic POSIX signal related constants as SIGRTMIN and SIGRTMAX. 

They described for example here: http://en.wikipedia.org/wiki/SIGRTMIN

Moreover it's even mentioned in file itself:

/*
 * XXX missing SIGRTMIN, SIGRTMAX.
 */

Absence of this variables makes porting of POSIX-compliant applications harder as well as lowers general POSIX-compliance of FreeBSD.

Actually, signal.h looks quite scary with all that:
/*
 * XXX missing SIG_HOLD.
 */

/*
 * XXX missing SIGEV_THREAD.
 */



>How-To-Repeat:


 less /usr/include/sys/signal.h



>Fix:


It'll be nice if that definitions were added to the signal.h ASAP. I don't see any strong reason not to have them.

With regards,
Timur Bakeyev.
