I had the same problem with libccp4. Upstream has recommended turning
off argument mismatch checks via FFLAGS, which I did in debian/rules [1]:

FFLAGS += -fallow-argument-mismatch

Of course this just silences the error, which should probably be fixed,
especially if argument mismatch is not intentional.

Hope this helps,
