#1911: -w doesn't turn off nullModuleExport

Os: Multiple |

Comment (by NeilMitchell):
In my example I initially got the above warning when compiling both module
A and module B. I then added -w to each file, and the B warning went away,
but not the A warning (the subject of this bug). I then modified the flags
in B to be only -fno-warn-unused-imports and the warning remained off -
namely that flag was suppressing the warning in module B.
It would seem logical if this warning could be suppressed by either -w or
-fno-warn-unused-imports
My example was slightly more complicated than just "module B where". I
tried to reduce a test case but replacing my complicated (but non-
exporting) module B with the above text removed the warning. Perhaps that
is another bug?
