Hmm, well, I suppose you're right. Still, the idea of removing the
dependency on DEFSYM-related globals would preclude the potential
optimization of putting these globals into a table at compile-time.
I suppose that part of the issue is that I don't add or remove
DEFSYMs very often, so even aside from the precluded optimization
I'm reluctant to complicate the build system just to save a few
build-time cycles on these rare occasions.

I was thinking of something even simpler: no macros at all.
If the C source code mentions an identifier Qfoo_bar, make-docfile
automatically generates the Lisp symbol foo-bar. To aid transition
we could make DEFSYM a no-op, or we could go through the code and
eliminate all the DEFSYM calls. (This would all be done after the
current patch is installed, of course.)
