For overlay mode, anything we fill in `hdr/fenv_macros.h` should only be used internally.  So it is kind of the best place to filling in any macros that are missing from the system/compiler headers.  And if it's not presented in the system header, it shouldn't matter much which value you assign to it, as long as it is different from the rest of the `FE_*` right?
