There is the plan to teach libcpp about Fortran comments and string
handling, which is a prerequisite for running CPP in not in the
-traditional mode. However, it is unclear when this project will be
completed. Would you be interested to work on it? (gfortran always needs
helping hands; essentially all who work on gfortran do so in their spare
time and have a background in physics, chemistry, meteorolgy etc.)

See e.g. the following bug report, which also has a preliminary patch
(Fortran comments) but lacks the Fortran string support.
