FreeDOS uses FreeCOM. Here I was using 0.84-pre2, but some prefer
0.82pl3 for its alleged better stability. (I've never had any issues
with either.) But 0.82pl3 doesn't support LFNs or DESCRIPT.IONs, and
0.84-pre2 only supports all features in 186 (not 8086) compiles. So
it's a (small) tradeoff.

(0.82pl3 download):
http://sourceforge.net/project/showfiles.php?group_id=3D5109&package_id=3D9=
826&release_id=3D203962

(0.84-pre2 download, command[xs].zip):
http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.0/p=
kgs/

(4DOS 8.00, final Lucho release):
http://4dos.zzl.org/

Anyways, long story short, it seems FreeCOM (either version) reports
"E:\EMACS" while 4DOS reports "e:\emacs". I can't imagine that
something so silly as case sensitivity could be the trouble, but
apparently it is!

Since I don't think it would even work with any non-GNU (and non-
DJGPP) make anyways, I think that's a fair suggestion. /current/3.79.1
and /beta/3.81 are the latest available for DJGPP anyways, so it's
fair to assume everyone already has one of them by now. I've even seen
a few other projects claim to require 3.81 or newer. So it wouldn't be
far out to assume 3.77+ for Emacs.

Sorry, my bad. I never installed (or intended to install) the full GNU
Emacs into the DJGPP directory. While the idea isn't bad, I dislike
making my setup too unwieldy, so I build it and even use it
separately. But when building, obviously %DJGPP% is set, which loads
DJGPP.ENV, which sets INFOPATH. In other words, it works fine without
%DJGPP% set (Emacs can load its own Info files fine via C-h i). So
never mind.   ;-)

Wow, the smallest upgrade in the history of the universe. Taking a big
risk, eh? Living on the bleeding edge?   ;-)    j/k
