If this were the case, it would manifest itself on all systems (not just AIX).

I'm gonna try to build this thing in PASE and see what I get.

I can only come up with one scenario that might produce the "warning:
incompatible implicit declaration of built-in function malloc" error like
this on AIX 5.3, given that<stdlib.h> is included in the source. That would
be the situation where some piece of code (perhaps a macro) uses the malloc
function before<stdlib.h> is included. See the following example:

void *myFunc(int size) {
void *ptr ;
ptr = malloc(size) ;


int main(int argc, char *argv[]) {
char *dummy ;
dummy = myFunc(1024) ;

This could be innocently manifest with code that would look like this:

#include "myFunc.h"

(where myFunc.h incorrectly contains the code rather than just a prototype.)

Unfortunately, I have yet to prove this theory on an AIX 5.3 system. Maybe
Alberto or Mark could?

Is it possible that repositioning the #include would provide benefit? (I
have yet to see the source.)
