Here's what the gcc manual says on the topic.  ("-Wpedantic" and
"-pedantic" are synonymous.)

     Some users try to use '-Wpedantic' to check programs for strict ISO
     C conformance.  They soon find that it does not do quite what they
     want: it finds some non-ISO practices, but not all--only those for
     which ISO C _requires_ a diagnostic, and some others for which
     diagnostics have been added.

     A feature to report any failure to conform to ISO C might be useful
     in some instances, but would require considerable additional work
     and would be quite different from '-Wpedantic'.  We don't have
     plans to support such a feature in the near future.
