You may want to wait for others to speak up; my opinion may be
controversial and not shared.

One way is "reasonable POSIX-like operating system", and I think that's
accurate.

But if you're going to list specific systems, then I was pointing out
one that you left out (I maintain the pkgsrc (portable packaging system
that is standard on NetBSD) entry for tahoe).  There's a big difference
between programs that are in theory portable to any POSIX-compliant
system, and programs that are known to work on multiple systems; tahoe
is one of the latter.

I see.  I have no idea about anything on Windows :-)
