So if I type say a + 2**33 at GCC (with proper expansion of 2**33
of course) it will do a single addqd?  Cool, I definately would
not have bothered with that, I was just going to do the -7..8 stuff.

Thanks, I did not know what needed to be done on this one.  Have
you noticed any improvements with the new mods?  I've been having
problems getting NetBSD-current to compile.  (makefiles not being
able to cd into directories, etc.)  So I haven't really gotten
anything much done with it yet.
