--- Comment #2 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- (In reply to Marek Polacek from comment #1) > and then we could use from_macro_expansion_at and don't warn if it's true. > But the problem is with -ftrack-macro-expansion=0, since > from_macro_expansion_at wouldn't work :(. I think warning in that case (returning false in the macro) is fair. One cannot expect to turn off features and get the same quality. Is ftrack-macro-expansion=0 used when bootstrapping gcc?
