Sorry, I should have mentioned that I'm the maintainer of CC Mode. I'm
looking for a solution that would be, as far as possible, invisible to
XEmacs users. Maybe I should check the size of cc-align.elc at
initialisation time, and `byte-compile-file' it if it's too small.
It would be nicer still to fix the byte compiler.
