So, keep it around, and make it that much easier to do the wrong
thing?

anything.  I mean, look at the set of systems which have been declared

share?  What use is the definition?


At worst, if needing -Dunix is the only problem that a program has,
you stuff -Dunix in the makefile.

However, i'd bet that 'long != 32 bits on all NetBSD ports', the
randomly migrating sys_errlist, etc. are all going to cause more
problems than the presence or lack of -Dunix.
