Be care. You are using the same macro _FENV_H for
libc/machine/spu/sys/fenv.h.

I'm not sure, but it seems preferable to do so.

BTW, I don't know how the fenv functions should behave in
multi-threading environment, i.e., should the fenv functions affect
only the current thread ? If so, I suppose that fenv status should be
managed by using _reent structure and that reentrant versions of fenv
functions should be also declared in fenv.h...
