While you're touching this area, can you change this to uppercase, as is 
the convention elsewhere?

As far as the patch itself goes, does -Wunused-parameter affect warnings 
for unused dummy arguments in Fortran code?  In that case, your patch 
may not be the right thing, otherwise I'm all in favor of applying it.

Thanks,
