[Bug fortran/31588] gfortran should be able to output Makefile dependencies with -M* options

[dfranke at gcc dot gnu dot org]

------- Comment #13 from dfranke at gcc dot gnu dot org  2010-06-12 21:06 -------
Would it be ok to require '-cpp' with '-M' or shall '-M' work without explicit
preprocessing enabled? In the latter case, would it be ok to enable
preprocessing implicitly?
