Compiling Elm 2.1 on the Unix PC

[Ed Horch]

FYI-

I had no trouble bringing up Elm 2.1 Patchlevel 1 on argon last
night.  In the Makefiles, I changed the LIBS value from "-ltermcap" to
"-lcurses" so the Unix PC would use the terminfo package, and for the
loading phase, I used the recently-posted "shcc" utility to use the
shared library.  Also, I had to take the "-n" out of the Elm
makefile's ${CC} line.

Were I more adventurous, I would have added another option to the
Configure script do to the Unix PC-specific stuff, but the hacks were
so minor it was easy to do them by hand.

(Argon's specifics: 1.5MB RAM, 67MB disk, v3.5 O/S)
