I've got a a freshly installed OSR 5.0.6 system, and an old one, for
which the Skunkware emacs and xemacs stopped working after the rs506a,
oss646c, gwxlibs-2.1.0Ba, and other patches.

I can live with my manually compiled xemacs, but I'd prefer emacs (due
to familiarity: I prefer its handling of RCS files and C indenting).
But getting a workable one, with SCO terminal settings, cleanly
compiled seems rather difficult. Has anyone got a good working emacs
for OSR 5.0.6 with all the updates?

Compiling the latest raw tarball, using the 'gnutools' package from
OSR 5.0.7, chokes on compiling 'maillock'.
