nn on xenix 386

[Chip Rosenthal]

The "nn" news reader is very close to working on SCO XENIX 386.

There are two bugs.  In "xmakefile", change near the bottom

    * this is probably non-portable so it is ifdef'ed

to:

    * this is probably non-portable so it is ifdef-ed
					     ^^^^^^^^

Cpp is used to generate the makefile, and the unbalanced quote causes problems.
Similar problems at the top of "prefix.sh".  I changed:

    WARNING: DON'T CHANGE THE ORDER OR CONTENTS OF THE FOLLOWING LINES

to:

    WARNING: DO NOT CHANGE THE ORDER OR CONTENTS OF THE FOLLOWING LINES
	     ^^^^^^

I've got a "m-i80386.h" and a "s-xenix386.h" if anybody wants to mess around
with this.  However, IMHO I haven't quite been convinced to give up rn yet.
