agreed - although I think removing the warnings is by itself a worthy
goal, as it effectively renders warnings useless ATM (since there are
so many false alarms). The solution is to compile those fortran
libraries differently - adding maybe an option to build_clib to
disable warnings or something.

I think ralf's point is that when you have many false alarms, the
legitimate ones are ignored.
