Yes, it does. > And the default is 32-bit.

I.e. DF is disabled for good. Usually I built RX stuff always with -m64bit-doubles because of that. It should be actually the default and -m32bit-doubles should be some kind of "optimization" switch. So in my optinion, -m64bit- doubles should be the default for a linux target, to allow having actual doubles, and not just floats. Cheers, Oleg
