Wow, that C program is really fast, especially with the -O3 option.

Too bad there wasn't a way to hook your spiffy ultra-fast C loop into
Ruby.  Wouldn't that be great?  Some kind of "C" extension thing.

Then, your Ruby (and any language that can 'hook' C) is basically as fast
as C or even Assembler if you really get desperate.

Too bad that didn't exist.  Oh well, I guess you'll have to keep testing
these loops and comparing them with Perl.
