I can't see a single reason for -fno-whole-file as a way to change
what the Fortran frontend presents to the middle-end. I have no idea
on whether it is useful to disable the extra warnings or errors the
Frontend produces with -fwhole-file -- for example the C and C++
frontends provide a -fpermissive option that turns some errors into warnings.
