From the IRIX signal(2) manpage

     C:
       void (*signal (int sig, void (*func)()))();
     C++:
       void (*signal (int sig, void (*func)(int)))(int);

     #if _XOPEN_SOURCE
       void (*signal (int sig, void (*func)(int)))(int);
     #endif

So it looks like an additional test in the configure script and
setting _XOPEN_SOURCE should get the right proto.  Not that I've
tested this nor checked with other things _XOPEN_SOURCE affects.

Alternatively...

     #define _BSD_SIGNALS or _BSD_COMPAT before including <signal.h>
and you get the slightly different and non-SYSV-compatible BSD proto:
     int (*signal(int sig, int (*func)(int, ...)))(int, ...);
