Actually, I just stopped compiling tn3270. :-)

Hmm. Definitly new .c.o rules. But how much else would we need? I don't
think we need all of the bsd.*.mk hierarchy to work for HOST_PROG; the
idea is it's just for little programs needed to compile a program which is
part of the os.

Or, if we're trying to compile a really complicated "host" program, we
really shouldn't be doing it within the build system. We should just build
the program out-right and then use it. So I think it's ok to not expect a
HOST_PROG system to be as full-featured as the normal bsd.*.mk files. You
should NOT need a library for a "host" program, nor do I think machine
language would be reasonable.

I think that all the changes could be localized to, in
something like the .if defined(PROG) section.

Or am I way off?

Take care,
