I just compiled make itself using gcc 3.2.1, (the compiler version 
that was giving me the problem) and the problem goes away when
I use my new make.

So it certainly appears that I introduced a strange incompatibility
by compiling make using a different compiler than my test program.
I just can't explain exactly what the incompatibity is, and why it
doesn't occur between bash and my test program.

To test my theory that perhaps the same glibc version that a calling
program uses must be used by programs it launches with the shell,
I created a test program calling system:

#include <stdlib.h>
int main()
{
   return system("./return0throw");
}

However, even when I compile this program with gcc 2.95.3 and compile
the return0throw program using 3.2.1, the program correctly returns 0.
