3.4.35 –fpp

Force preprocessing of input with fpp.

Pass all the input source files listed on the f95 command line through the fpp preprocessor, regardless of file extension. (Normally, only files with .F, .F90, or .F95 extension are automatically preprocessed by fpp.) See also 3.4.162 –xpp={fpp|cpp}.
