--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Confirmed on trunk (6.0) too. This has probably never worked: with 4.7.3 I get

f951: error: -Werror=compare-reals: no option -Wcompare-reals

> Just noticed the same applies to -Wunused-parameter.

Can you please post a test?
