After looking more closely I see you didn't actually *remove* those
macros, just define them in a different place/way.  So the above objection
is just noise, sorry.  (Though I think it'd be notationally cleaner to let
configure continue to define the macros; it doesn't need to do anything as
ugly as CppAsString2() to concatenate...)
