This email follows up on a thread with an earlier version of this patch
<http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00398.html>
to remove src/m/* from Emacs. I am sending this to bug-gnu-emacs
so it gets a proper bug number.)

I came up with a better idea, which is to stop using symbols like BITS_PER_LONG
in #if. The symbols can then be made enums, which is nicer, as
they're visible to debuggers. Here is a revised patch.
This is tested on 32- and 64- bit x86 GNU/Linux and sparc Solaris
but I want to test it more before it goes in.
