GCC already has implicit knowledge of how FE_* for exceptions relate to=20
the hardware, because it generates calls to __atomic_feraiseexcept, which=20
is defined in libatomic using FE_* from <fenv.h>.  I think SPARC Solaris=20
is the only case where this actually turned out to be OS-specific (see=20
SPARC_LOW_FE_EXCEPT_VALUES).=
