Fourth occurance of the string `signal' I found in the autoconf manual:

- Macro: AC_TYPE_SIGNAL
    If `signal.h' declares `signal' as returning a pointer to a
    function returning `void', define `RETSIGTYPE' to be `void';
    otherwise, define it to be `int'.

    Define signal handlers as returning type `RETSIGTYPE':

         RETSIGTYPE
         hup_handler ()
         {
         ...
         }
