Howdy:
	While I was completeing the port of my application to ANSI-C, I came
across this:

#include <signal.h>
#include "myproto.h" /* This included many prototypes, but of particular
interest here is: void memory_fault(void); */

[...]

	if ((int) signal(SIGSEGV, memory_fault) < 0) {
		perror("Trouble initializing SEGV routine");
		exit(-1);
	}

Under AIX 3.2 using c89, this produces a diagnostic about incompatible types:
int and pointer (don't have the exact text handy, but I hope you get the
idea). This occurs IFF memory_fault() is declared AFTER its use or in another
module, if it is declared before its use there is no diagnostic. The fix is
simple, ((void *) memory_fault) works fine but I THINK that it is unnecessary.

Now I know that a conforming implementation is allowed to issue any spurious
diagnostics that it wishes to but ...

Am I all wet here or should I make a call to IBM to ask for a fix (I mean, it
made me wonder whether the prototypes were being used at all (they are)).

what say you?
