Well, my problem w.r.t -mips1 -mlong64 is that it's allegedly
supported, and coping with it in code which needs to handle lots of
options gracefully... makes for a problem.

It causes the one case for mips GCC currently where sizeof long !=
sizeof pointer.  8-)

yes, long long is still a pain, but it's a slightly different pain.

Yes.  There are a LOT of people doing that.
