--- Comment #3 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
I'm pretty sure that this applies to all pedantic warnings that occur while
preprocessing:
const int a0 = 0b101010;
const int a1 = __extension__ 0b101010;
C++ lexes everything at once without parsing __extension__.
Same problem with pragma diagnostics (bug 53431).
Either these warnings are moved from the preprocessor to the FE, that is,
somehow delayed, or the preprocessor has to learn about __extension__ and
pragma diagnostics.
I'm surprised there is no older report about this.
