more on 2.99.48 on SunOS 4.1.3_U1

[Scott Ballantyne <sdb@redhotmomma.ssr.com>]

In zmsignal.h you have defined:

#define SIGNAL_RELEASE(SIG) \
	sigsetmask(~sigmask(SIG) & sigblock(SIG_HOLD(sig)))

This doesn't work on SunOS 4.1.3_U1, since SIG_HOLD is defined as 

#define	SIG_HOLD	(void (*)())3

Not sure what to suggest here...
