A couple of weeks ago I submitted a patch to fix configure --with-tcl.

However somebody else also applied a patch to the same part of
configure to fix a different problem. So part of my patch was not
applied or got reversed or ... whatever.

The attached patch will restore configure --with-tcl to working
order and should remove a lot of the messages complaining about
tcl not working.
