Ugly workaround

xcb_discard_reply() was added in libxcb 1.6, released April 2010. Configure
currently checks for xcb >= 1.1.92 since that is when xcb_take_socket() was
added, although this function isn't used anymore.

Which version of libxcb do you have?

Attached is a patch which forces a round trip instead of using
xcb_discard_reply(). I think a better fix would be to add a check for
xcb_discard_reply() to configure and skip the whole "if (might_reuse)" block if
we don't have that function. I guess I'll be building old xcb versions.
