We used to say that if your code built and worked on both Ultrix and
Unicos you could be pretty sure it would work on any Unix. :-)

Yes, we worked around the broken <sys/socket.h> in krb4.  We can steal
the same kludge for heimdal.

Hm, I don't remember having seen this before.

I think what you're seeing here is the two calls to `rresvport' at the
begin of main().  To be able to handle `bsd-style' privledged port
"authentication" in rsh, it always tries to allocate two ports at then
does setuid().

Hm, another function to implement in roken.

Ok, socket stuff has moved in roken so I don't think this should occur
any longer.
