In signal.c we find the lines

/* catcher -- catch (and defer) a signal from the kernel */
static void catcher(int sig) {
#if SYSV_SIGNALS /* only do this for unreliable signals */
	signal(sig, catcher);
#endif

maybe SYSV_SIGNALS ought to be true for HPUX systems?  Try adding the lines

#ifndef	SYSV_SIGNALS
#define	SYSV_SIGNALS		1
#endif

after the line saying

#if HPUX

and tell ut how it worked out.
