Thanks Steven.  I looked at these and indeed there are quite a few changes.

As you mention below, some of the coding is quite ugly!

I've just let the ckvker.com DCL build file detect I'm using Multinet.

There's existing comments in ckcmai.c regarding a clash with Multinet
and the inclusion of <sys/time.h>.

This causes a compilation error with incompatible type for the 5th parameter to
the select() routine.  The default expects a "struct timeval" type,  whereas Multinet
uses "void".  To fix this I included the Multinet version of time.h from the
multinet_root:[multinet.include.sys] directory in ckcmai.c (using #ifdef MULTINET
conditional).
