[My SMTP server refuses to send mail to address@hidden so I have
to post this here instead.  Hope someone in charge sees it]  

In GNU Emacs 21.1.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2001-10-21 on rocksteady
Important settings:
  value of $LC_ALL: C
  value of $LC_COLLATE: nil
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: en_US
  locale-coding-system: nil
  default-enable-multibyte-characters: t

Setting the variable `compilation-window-height' causes M-x compile to
fail with the following backtrace when the value is larger than the
whole Emacs window (as can be the case when running Emacs on the

Debugger entered--Lisp error: (wrong-type-argument window-live-p #<window 1>)
  select-window(#<window 1>)
  compilation-set-window-height(#<window 4 on *compilation*>)
  compile-internal("make -k " "No more errors")
  compile("make -k ")

Here is a patch that fixes the problem.  I suppose this really should be
handled in the built-in `enlarge-window' for a more general approach.
