Not every platform defines all the weak no-op pthread stubs we use. Diego 'Flameeyes' Pettenò has been working on a patch; I'm opening this bug to help us not forget about it. The mailing list threads start with http://lists.freedesktop.org/archives/xcb/2006-November/002230.html http://lists.freedesktop.org/archives/xcb/2006-November/002260.html http://lists.freedesktop.org/archives/xcb/2006-November/002311.html though of course Pipermail loses on GPG-signed mail, as usual.
Also see <http://lists.freedesktop.org/archives/xcb/2006-September/002070.html>, and I think the portability problem may have come up in discussion before that.
We've pushed a change to libxcb to use our new libpthread-stubs component. We believe this bug is now fixed.
