Only on those built --with-wide-int, right?  Because otherwise, a
32-bit 'long' is just fine with GMP.

I see no reason to worry about slightly less efficient bignums on some

should ask the GMP developers to make those changes sooner rather than
later, to expedite the process.  After all, they should care about
Emacs, I think.
