"Portability" is portability.  Slice and dice it other ways if you

Agreed but...

Why not?  Good code (which I believe has always been one of the
underlying principles of NetBSD development) should be portable.
I disagree with every usr.bin/foo having a GNU configure script.
(Gross!  Why on earth GNU configure?  It certainly is not the be-all
end-all of portability.) Portable code makes for good code.  What
you maybe able to get away with under one OS/compiler combination
may bite you on another.  It can help point out sloppy code.

This is one approach I suppose.  I think that this case is a bit
different based on the history of theses applications.

Is there a publicly accessible CVS repository for lukemftp?

I fairly certain that the telnet/telnetd in Solaris and IRIX are
still based on the 4.3BSD sources.  They do not include the changes
that Dave Borman (once of Cray Research) contributed back to Berkeley
and were a part of the 4.4BSD releases.  I also believe that this
(not keeping up) is why, although I can confirm, the #ifdef's for
other OSes were added.
