First off, the '/usr/lpp/bos/bsdport' document that you refer to is strictly
for AIX v3 - this runs on the RISC System/6000 (not the RT).  There are a 
couple of things to note when porting software to the RT from a Berkley based
system.

First off, while a lot of the Berkley features are in AIX 2.2.1, it is basic-
ally an AT&T SysV.2 system with parts of SysV.3 added.  You might be able to
find a #define in your code for SYSV - but not necessarily.

Secondly, to make the RT compile more like a BSD-type Unix(tm) box, you need
to do the following in your compile line:

            cc -DBSD_INCLUDES <other flags> <file names> -lbsd

I'm pretty sure those are both correct.  If you want a little bit more infor-
mation, look at the README file located in the / directory.  More specifically
the section on TCP/IP for the PC which talks about compiling a particular
daemon for facilitating mail.  That daemon was pure Berkley code when origin-
ally written and there is a compile line in there that should help.
