--- Comment #4 from David Malcolm <dmalcolm at gcc dot gnu.org> --- (In reply to Zack Weinberg from comment #3) > Maybe name_reserved_for_implementation_p should be a langhook? I'm only using it in the C/C++ frontends, and the implementation is identical for both, so I don't think so - unless I'm missing something? I'm working on a version of the patch that moves the macro-spellchecking to c-family.
