Why am I getting 0 for output here when unsigned long's are 32 bits with the
Quick C Version 2.5 compiler?  (Casting everything to unsigned long does not
help).

* #include <stdio.h>
* main() {
*    unsigned long M = 34;
*    printf("%08x\n", M << 16);
* }

This is a compiler bug, according to my understanding of the Quick C manual
and C language.
