--- Comment #3 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- FWIW, the Ada front end has some style checking support (I once broke bootstrap by applying spelling corrections there, where fixing the spelling in a comment made a line too long). It wouldn't be ridiculous to have such checks available for C and C++, so far as formatting checks work reasonably in the presence of macros.
