Fortran these days has integrated preprocessor, I doubt fpp would be of any use and you'd need to define how exactly should "fortran" preprocessing behave (e.g. how it is different from assembly preprocessing). Note that even -E -xassembler-with-cpp preprocessing includes stdc-predef.h by default, you need to use -nostdinc to avoid that. In any case, not a bug IMHO.
