Fortran that uses a preprocessor commonly uses the pre-ANSI C
preprocessor.  There are some legal Fortran character sequences
that cause problems with the ANSI version.

As the subject is Fortran, that might be significant.  
(Many Fortran compilers have the ability to call the C preprocessor
to process the input before compiling it.)
