  It's questionable whether its a bug or not.  The Sun man page reads:

     The handler routine can be declared:

         handler(sig, code, scp)
         int sig, code;
         struct sigcontext *scp;


  What bothers me about this entry is it doesn't say you have to
declare the function that way.  There's no entry in the BUGS
section eluding to what happen if you don't conform either.
