Versoin 6 of Icon nas been installed on a VAX-11/750 under the "Ninth
Edition" of UNIX (also referred to as "Version 9").  The config.trl
file here is from that implementation.

Because of the built-in libraries in Version 9, it is necessary to
remove the -lm in the Makefiles for iconx and pi.  This can be
done manual after the setup, or they can be removed on an ad hoc basis
from ../Generic/iconx.make and ../Generic/pi.make.
