Re: Tn5250 compile under IBM Aix 5.3

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) ;
    }

#include <stdlib.h>

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"
#include <stdlib.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.)

Harumph! I'll have a look this PM. There has to be a simple explanation.

    Yes, stdlib.h is included by tn5250-private.h, which in turn is
    included
    throughout the source of tn5250.
