It might make more sense to have a "type" field which holds
a Lisp_Object so we can trivially make it unique by using an object that
we just allocated.

Right, those headers need to be provided by Emacs.

If we let Emacs run the C compiler, it can trivially add the -I args
to specify where those headers are found. This way they don't need to
be installed in the system's include dir (which is always a problem for
non-root users, and makes it more tricky to handle multiple installs of
different Emacs versions).

I don't think so. But we can copy the config.h (and whichever other
include file we might need) when installing Emacs.

Yup!

Yay!
