Unfortunetly, this way doesn't work as expected, since cpp warns when
a symbol is parsed (not when evaluated).

So, we needs another fix.  Probably, possible ways are:

(1) change cpp so that above trick works.

(2) predefine __unix__ in cc (again) and test it.

(3) test only __NetBSD__

Since that the meaning of that test is whether target system is unix
variant (against vms or msdos) or not, probably (2) is better, isn't
