EMACS enviroment variable wrong in M-x compile

["David Kågedal" <davidk@lysator.liu.se>]

In GNU Emacs 21.2.1 (i386-debian-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2002-03-22 on raven, modified by Debian
configured using `configure  i386-debian-linux-gnu --prefix=/usr --sharedstatedir=/var/lib --libexecdir=/usr/lib --localstatedir=/var/lib --infodir=/usr/share/info --mandir=/usr/share/man --with-pop=yes --with-x=yes --with-x-toolkit=athena --without-gif'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In Emacs 21.2 (from debian package emacs21 21.2-1), a change in
compile.el was introduced (but not mentioned in NEWS of even the
changelog) so that it doesn't set EMACS in the environment when
running compilation processes.  Unfortunately, the test seems to be
inverted.

compile.el:844:
	      (if (getenv "EMACS")
		  (setq process-environment
			(cons "EMACS=t" process-environment)))

Shouldn't the test be (not (getenv "EMACS"))?  As it is now, $EMACS
won't get set for me.
