No, that is wrong; by design this structure initialization should happen before the options from the command line (including -On) have their effects. Rather, I think -fno-fast-math - whether explicit or implicit - should not be overriding such language-dependent defaults for particular options; if a language defaults to -fno-math-errno, explicit -fmath-errno should be required to override that (essentially, the set of options implied by -ffast-math / -fno-fast-math should depend on the language). -- Joseph S.
