--with-gtk-version option to configure, so you can explicitly tell it

[sgt/putty] / unix / configure.ac

# To compile this into a configure script, you need:
# * Autoconf 2.50 or newer
# * Gtk (for $prefix/share/aclocal/gtk.m4)
# * Automake (for aclocal)
# If you've got them, running "autoreconf" should work.
