The asm routines are the most important thing for speed in gmp.  After
that we usually recommend gcc, since it gets various inline asm
blocks.  The generated perl stuff is pretty straightfoward and
unlikely to be affected one way or the other.

Ah yes, I might change that.

More functions was the aim.

It was easier to get started just chucking it in the gmp sources.  I
suppose at least a cross reference in cpan would be nice.

I hadn't wanted to worry about being Math::BigInt compatible, so did
something new.  I think BigInt was a bit bare when I'd first looked at
it too.  Seems to have grown since then, might be the way to go for
the future.
