Re: GTK patches part 1

[Richard Stallman]

    One important thing about --with-gtk is that it's really
    --with-gtk=/path, which allows you to specify which gtk to use.
    (--with-gtk is a degenerate case which says use gtk wherever you can
    find it.)

A --with option is not supposed to take a directory name argumemt.
>From the GNU coding standards:

    Do not use a @samp{--with} option to specify the file name to use to
    find certain files.  That is outside the scope of what @samp{--with}
    options are for.

--with-gtk should mean "use GTK" and nothing else.
