In 1.4.2, the "FOO=BAR" parsing code in runtest.exp was
moved into the first pass through the command line but
was not taken care of in the second pass. This is what
causes the error. So both 1.4.1 and 1.4.3 are OK but not
1.4.2.

You can check if your (unpatched) version is OK by running

    runtest FOO=bar --version

This should set the Tcl variable FOO to bar and not
cause an error.

In fact this seems to be one of the more commonly
asked questions on the dejagnu lists:

http://mail.gnu.org/archive/html/bug-dejagnu/2002-09/msg00006.html

etc.
