A module file with an incorrect checksum might still be valid or useful, so I didn't want the error to be fatal.  Sometimes it is useful (but dangerous) to be able to modify a module file by hand.

If you must turn these warnings into unconditional errors, then Fortran::common::UsageWarning::ModuleFile will become obsolete and should be deleted.
