[Xcb] [PATCH:xwininfo] Make xcb-icccm dependency be optional and off-by-default
Alan Coopersmith
alan.coopersmith at oracle.com
Fri Jun 25 21:46:34 PDT 2010
Changes to the xcb-icccm API/ABI are under discussion, so for now default
to using local property handling code modeled after the current API, with
a --with-xcb-icccm to enable use of the API for testing/development.
Once the API/ABI is stable & released, this set of changes should be
removed and the xcb-icccm API just used directly.
