In order to not trigger a compilation cascade, gfortran only overwrites a .mod
file when its MD5 sum has changed.
Seemingly, the mod-file versioning has the side effect that the MOD file is not
overwritten if there are no other changes but the version number, which causes
the version-mismatch error.
I'm not sure whether this is a problem between 4.x and 4.(x+1) versions as the
.mod file probably has changed in an incompatible way (different MD5 sum), but
still it is annoying.
Expected: If the version number does not match, the file is written
nevertheless.
(Maybe the error also occurs at a different place, I have not yet checked the
source code.)

Confirmed.
This scared the pants off me by apparently causing regressions and then a build
failure in libgomp.
Cheers
Paul
