No, the goal of -pedantic-errors is not to be a portability checker or
conformance tester.

It's to disable standard-conflicting GNU extensions so that you get an
error when the standard requires a diagnostic.

On the other hand, we have -Wc90-c99-compat "Warn about features notpresent in ISO C90, but present in ISO C99." which might be an ok place toadd a warning about stdint.h (or not).
