Well, the question that comes to mind is, is there a flag with which we
could silence the compiler?  The user might just not want to read that
NOTICE.

If not, then I'd squash the two patches together (is there a point in
keeping them separate?), and relax the sed pattern to kill all lines
matching '^NOTICE:'.  Even that might eventually not be enough with
localization, but at least then you aren't relying on specific compiler
flags that might not be valid with a different compiler version, or
different flags in $FCFLAGS or $FFLAGS.

Thanks,
Ralf
