  No, I did not know about the -N option.  Tried that (once I found the
correct location) and it worked.  Even more surprising was when I upped the
optimization level---the compiler (in this case, GCC 2.7.2.3) *inlined* the
sort routine in sort_ascending() and sort_descending(), so even if I got the
right instruction changed, it wouldn't work because the code that was
modified was never called.

  Not that I would do this, even for throw away stuff, but it's nice to know
it's there if needed.
