Thanks for the offer Richard. I have moved beyond the problem.
I have what I need with the 11.2.0 compiler and the 6.12.12 kernel.

I think this will give an example of what I found:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <termio.h>
#include <sys/wait.h>
#include <signal.h>
#include <time.h>
#include <sys/time.h>
#include <string.h>
#include <ctype.h>

int main();

//lots more code in here

int main(argc,argv)
int argc;
char *argv[];
{
exit(0);
}

The command first command would have been
simply gcc program.c -o program

then I tried stuff like:

gcc --std=gnu89 program.c -o program

The actual program I looked at had used forward
references and I put a large number of the
declarations up front. The new compiler flagged
the redefinitions as errors, not warnings as
might have been done with a duplicate #define.

I can't remember now what program it was, nor
for what compiler I originally used that would
have allowed the forward references.
