Yes, furthermore it would hardly be a problem if CC Mode is more
lenient in this regard than the compiler.

Even in other versions there's the possibility to use \sw etc. The
problem has been that there's no character class that matches all
alphabetic characters but not the digits. However, you mentioned
[:alpha:] which would presumably do just that.

You said it works in Emacs 21, but I haven't been able to find any doc
on these new character classes in the manual for Emacs 21.2. Where can
I read about it?
