Indeed, we'd like to allow building with several GUI libs at the same
time, so it would be good to try and restructure this change so it
doesn't assume a single GUI library.  But in order to get such
a "multi-GUI" Emacs, we'll need to refactor a fair bit of the code, so
I'm not sure this change would be a real impediment.

Also, this "multi-GUI" goal is just a "would be nice to have" and while
someone mentioned interest in hacking on it a while ago, I don't think
he still plans to do it, and I don't know of anybody who does, so it may
stay as a wishlist item for many more years.

IOW, I don't think this patch 2/9 should worry too much about this issue.
