What gfortran should do is that if pedantic enables Wtabs, then the warnings
should be of the form:

if (pedantic && warn_tabs)
 pedantic("whatever");
else if (warn_tabs)
 warning("whatever");

pedantic() emits errors if -pedantic-errors, otherwise it emits warnings.
warning() emits errors if -Werror, otherwise it emits warnings.

I guess there would be similar functions in gfortran. (It would be great to
integrate the diagnostics machinery but making things work in a similar way is
already a step forward).
