Yes, the F90/F95/F2003 *.mod files are compiler- and target-specific.
As FX Coudert (one of the gfortran developers) pointed out:

  http://gcc.gnu.org/ml/fortran/2007-10/msg00306.html

it may be best to treat the *.mod files more like libraries (and less
like headers).  FX's recommendation was:

  /usr/lib*/finclude or /usr/finclude* where * can be 32, 64 or nothing

which is quite similar to Spot's "I like this the best so far" comment
regarding the location:

   %{_libdir}/gfortran/modules

So are we reaching a consensus here on "%{_libdir}/gfortran/modules"?
Does anyone have any technical objections to it?
