Does Execute always return -1?  In the following code, caller always
prints "Success = -1", regardless of the value of N in callee.c, or even
if callee does not exist.  Why?  What is "the right way" to get the 
return code from Execute?

caller.c
--------
main()
{
	int success;
	success = Execute ("callee",0,0);
	printf("Success = %d\n",success);
}

callee.c
--------
#define N 0
main()
{
	printf("Callee Exiting with return code %d\n",N);
	exit(N);
}

Thanks in advance,
