Description

=begin
Mentioned here:
http://rubyforge.org/tracker/?group_id=426&atid=1698&func=detail&aid=19034
This improves gcd performance by about 300%
I assume this patch is still valid, if not I could come up with a new one.
Thanks!

=begin
I think embedding of Rational already made same result. It internally uses long type of C for Fixnums.

This patch may be still meaningful for 1.8. But extension of Fixnum needs discussion.
