+Yes, thanks.  I've included a revised version of my patch below.

+
+Well, gdbarch is never supposed to change the default behavior of
+macros; this helps us convert pre-gdbarch targets incrementally.
+Simply turning on gdbarch for one's target ideally wouldn't change its
+behavior at all.

+gdb fails to build from source on m68k because some definitions have
