Stephen,

The build problem went away when I checked out the source again using the tag
'r21-5-13', and running "cvs diff -r r21-5-13" as you suggested indicates that
I do now have a valid source tree. However, I still have the runtime problem
with the mark. I've tried renaming my $HOME/.emacs file (I've not converted to
$HOME/.xemacs/init.el) to eliminate any possibility that something there is
causing the problem, but the behavior is identical.

Any time I try to set the mark with C-@ or M-x set-mark-command, I get the
message

Symbol's value as variable is void: region

with the following backtrace when debug-on-error is set to true

Signaling: (void-variable region)
  zmacs-make-extent-for-region((#<marker at 395 in *scratch* 0x1028c8dc> .
#<marker at 395 in *scratch* 0x1028c8c4>))
  zmacs-activate-region()
  push-mark(nil nil t)
  set-mark-command(nil)
  call-interactively(set-mark-command)
  command-execute(set-mark-command t)
  execute-extended-command(nil)
  call-interactively(execute-extended-command)

If I try highlighting text with the mouse, the text highlights as I drag the
mouse cursor, but I get the above message when I release the button, although
the backtrace is a bit different:

Signaling: (void-variable region)
  zmacs-make-extent-for-region((#<marker at 3 in *scratch* 0x1028c8dc> .

Just for completeness, here's the output of running "cvs diff -r r21-5-13"
against my current source tree:
