Daniel Franke <dfranke at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dfranke at gcc dot gnu.org --- Comment #6 from Daniel Franke <dfranke at gcc dot gnu.org> 2011-07-24 19:35:42 UTC --- See also #44526 (I think there's another related PR somewhere, can't find it right now). The -cpp is required as the C preprocesor and libcpp are being used to generate the Makefile dependencies. As you probably know, in itself Fortran doesn't really have a concept of a preprocessor.
