There're quite a few other such constructs.  Does it work under XEmacs?
If so which versions.  They're all things which are easy to check, but
cumulatively it's a massive time sink.

Again, what about XEmacs?

I'd agree with you about its eventual removal.  Clearly there was a big
problem to solve - something like cc-bytecomp.el doesn't get knocked
together in a couple of hours.  I suspect Martin Stjernholm was having
big problems with his various versions during development, and that
cc-bytecomp is more for me and colleagues rather than ordinary users.
