Also, the Python is only used to generate some generic C
code.  So if you want to stick with Xlib/XCB, just build
xcb/proto and xcb/libxcb on some machine with newer Python
and copy the generated C files over.

You should maybe file a couple of bugs against XCB: one
about not shipping generated C, and one about requiring
new-ish Python.  I'm thinking offhand that the right fix for
the generated C bug is to have a separate package (or two)
available with current generated files in it.  We may not be
able to reasonably fix the Python one, depending on how much
damage it would require to the current Python code).
