I was going to say that it didn't define it, but I looked at it again
and it turns out that it does.   So you're right - it can test that
instead.   However, the NetBSD/pmax compiler currently does define
__mips.

Almost certainly true.

There's no such predefine.   I suppose we could make there be one,
though.

Actually, I think for now the ifdef should read:

#if !defined(__svr4__) && !defined(__SVR4) && \
	!(defined (__NetBSD__) && (defined (__mips__) || defined (__alpha__)))

Does that work for you?
