Is there a non-default configuration where they are true?

I've been wavering on approving this patch, not because there's
anything wrong with it, but because I'm still ruminating on
https://gcc.gnu.org/ml/gcc-patches/2015-11/msg01458.html

I think I'm going to make that change for mingw-w64, but either way
the DJGPP patch is OK for trunk (assuming there is some non-default
configuration where it actually does something useful).
