Synopsis: __extension__ keyword doesn't suppress warning on LL or ULL constants

State-Changed-When: Mon Dec  9 15:10:17 2002
State-Changed-Why:
    I can confirm this on recent 3.3. The warning is from the preprocessor
    where we don't know about __extension__. Maybe the fix is to just
    document this. Anyway: Category changed to preprocessor and priority
    raised to medium because this is technically a regression.
