[Fortran,4.9/5/6 Regression]ICE for Fortran files when specifying a file instead of an include directory

[Jerry DeLisle]

The ice on this one is actually in libcpp but I don't want to mess around in
that area.  Not sure why we were only doing a warning here.

I plan to commit the following to trunk with a ChangeLog entry under the simple
and obvious rule.

Let me no if any objections.

Jerry
