@eugeneepshteyn, to resolve the remaining issue where valid Fortran constructs are misidentified as C comments, can we enable C-style comment parsing for label fields only when preprocessing is enabled?

Then, we can defer the discussion on guarding all C comments behind the preprocessing flag, matching gfortran and ifx, for the future.
