I'm not sure why NetBSD doesn't define __unix__; it is a good idea not
to define unix, since that is in the application's namespace, and
should not be defined by the compiler.

The define __unix__/__unix/unix, to my knowledge, is not covered by
any standard - it is merely a convention. POSIX systems identify
themselves with different defines.

Notice that FreeBSD defines unix, as does NetBSD on m68k. It may be a
mistake: what does the system compiler define?
