--- Comment #9 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Since at least 4.8 '-pedantic -Werror' gives an error;
% gfortran /opt/gcc/work/gcc/testsuite/gfortran.dg/c_by_val_4.f -c -pedantic
-Werror
/opt/gcc/work/gcc/testsuite/gfortran.dg/c_by_val_4.f:14:6:
CALL DOIT( %VAL( P ) ) ! { dg-warning "Extension: argument list
function" }

Error: Unclassifiable statement at (1)
/opt/gcc/work/gcc/testsuite/gfortran.dg/c_by_val_4.f:16:6:
CALL DOIT( %VAL( P ) ) ! { dg-warning "Extension: argument list
function" }

Error: Unclassifiable statement at (1)
but '-pedantic-errors' does not
% gfortran /opt/gcc/work/gcc/testsuite/gfortran.dg/c_by_val_4.f -c
-pedantic-errors
/opt/gcc/work/gcc/testsuite/gfortran.dg/c_by_val_4.f:14:22:

AFAICT '-pedantic-errors' is not handled by the gfortran FE.
Note that '-pedantic' may change a warning to an error:
% gfortran /opt/gcc/work/gcc/testsuite/gfortran.dg/hollerith8.f90 -pedantic
