I erroneously appended them to the other set of patches I sent
yesterday.  I attach it below again.

I didn't know that this was the case, but if it is so, I agree that
returning FP values in registers should be the default.

	* i386-tdep.c (i386_extract_return_value)
	[I386_AIX_TARGET || I386_GNULINUX_TARGET]: Add I386_DJGPP_TARGET
	to the list of targets which return FP values in FP registers.
