------- Comment #2 from brooks at gcc dot gnu dot org 2006-11-09 09:48 ------- -fpreprocessed seems to be intended for internal use between gfortran and f951, to indicate that the file has been preprocessed and the original filename should be read from it. Thus, it should probably be set to Undocumented in lang.opt.
