I hit exactly the same issue. The attached patch fixes the problem for
me, though I don't know ATM whether the choice I made is correct or only
works by accident.

Note also that this doesn't test for the API, so only apply this patch
when compiling for older Xservers. Unfortunately there's no easy way to
detect this ABI change. :-(
