--- Comment #5 from kargl at gcc dot gnu.org ---
See the documenation where it explicitly states:
Many Fortran compilers including GNU Fortran allow passing
the source code through a C preprocessor (CPP; sometimes
also called the Fortran preprocessor, FPP) to allow for
conditional compilation. In the case of GNU Fortran, this
is the GNU C Preprocessor in the traditional mode.
% ~/work/5/bin/cpp -I. -E -traditional-cpp u2.F
gives the same result as gfortran -I. -E u2.F.
Obvious workaround
cpp -I. -E file.F > file.f90
gfortran -c file.f90
