Actually, that patch was to fix my unix build.  The big change was that
zic no longer uses pgport routines, and that was done by someone else so
zic would be run on the target matchine for cross-platform builds.

I have applied the attached patch which should fix the problems you saw.
It basically extends NO_PGPORT, which I expected might be required when
I added it.
