    causes spurious byte compiler warnings:

      gnus-art.el:3549:4:Warning: assignment to free variable tool-bar-map

    for code like this:

      (set (make-local-variable 'tool-bar-map) gnus-summary-tool-bar-map)

It is right for set to issue warnings about undeclared variables
in this case.  However, tool-bar-map is declared, so it should not
get a warning.
