Related: All source-file reading should go though libcpp, which requires a
better white space handling; cf.

Slighly updated version. Set tradtional to 0 in fortran/cpp.c to enable new
features, which will fail if the following (work items) are in you Fortran
file:
- Spacing needs to be preserved for fixed-form Fortran
(currently fails in the test suite)
- Check that '...''...' work (seems so)
- Problem mentioned in comment 5
* Max linelength option for gfortran and cpp
* Fortran/Fixed-form-source Fortran for cpp
* Should one use c_lang instead of a flag? Advantage for c_lang: Fortran is a
language; advantage for flag: the CPP features can be tuned by c_lang.

Additional point, one needs to take care also of continuation lines of the
following kind. This should print "Hello Paul" and not "Hello Hans".
#define Paul Hans
! Paul's string
print *,'Hello &
&Paul'
end

One big problem which prevents omitting the -traditional-cpp is that comments
are not ignored. Another example of this is
! .... /*
which is regarded as the beginning of a C/C++ comment. Thus we should add two
modes to CPP, one for fixed-form and one for free-form Fortran code.

I though the -lang-fortran, which is passed (according to gfortran -###), takes
care of this?

Well, that I assumed. But it is still (somehow) based on ISO C's preprocessor.

One problem without using -tranditional-cpp is that some tokens in C are not
tokens in Fortran so you could get the wrong result. This is why
-tranditional-cpp is used.
There is no standard for Preprocessed Fortran Source at all.
