Not at the moment, no.  Possibly because people might write regexps as
loosely as your suggestion, and that would mangle CC Mode.  Whats wanted
would be something more precise like "ATTRIBUTE_[A-Z]*".

For macros with semicolons, I allowed a regexp to be entered directly
instead of a list of identifiers, but there it is mandatory that the
regexp not match anything but valid identifiers.  For noise macros, a
regexp just seems less needed, somehow.
