The module API was designed with the goal that a module compiled for a given version of Emacs will keep working with other versions, as long as they're more recent. For example recompiling --with-wide-int or --without-wide-int shouldn't affect the modules's binary compatibility. I don't know if it's crucial, but so far we have decided that it is and I don't think that bignums are a good reason to revert this decision. Stefan
