Hmm, returning an error contradicts a bit the manpage:

-pedantic
       Issue warnings for uses of extensions to FORTRAN 95.  -pedantic
       also applies to C-language constructs where they occur in
       GNU Fortran source files, such as use of \e in a character
       constant within a directive like #include.
-pedantic-errors
       Like -pedantic, except that errors are produced rather than
       warnings.

-Werror
       Turns all warnings into errors.
