Fixing this made me realize that some calls to DEFVAR_PER_BUFFER had to be updated to use Qfixnump rather than Qintegerp. (With the restrictions to be lifted piecemeal in the future.) Also the bytecode interpreter needed some updates; and I changed the emacs-module API to allow bigger-than-fixnum ints to be converted. I've implemented all my to-do items, except: * Update documentation * Use the mpn_ API. This does not look fun :-( I still haven't tried cons_to_unsigned et al, out of compatibility fears. I've cleaned up the series quite a bit so it is in decent shape if you want to read through it: git@github.com:tromey/emacs.git feature/bignum I tend to rebase and force-push for development branches like this, so beware of that. No ChangeLogs yet I'm afraid. Tom
