Changing Int to CInt and building with -D_XSERVER64 (when appropriate)
I am not sure if defining _XSERVER64 is the right fix. The Xlib headers say that: /* * _XSERVER64 must ONLY be defined when compiling X server sources on * systems where unsigned long is not 32 bits, must NOT be used in * client or library code. */ Apparently on the server, XID should be 32-bit but in client code it should be 64-bit (see, for example, http://lists.freedesktop.org/archives/xorg/2006-August/017515.html). This seems to cause a real problem in Xmonad, for example. If I have many windows open and start Xmonad, it scans for windows to manage via XQueryTree. I get the following list: [6291457,0,6291469,0,6291735,0,6291780,0,6292217,0,6292266] Each window has a 64-bit XID, but now the X11 bindings are processing them as an array of 32-bit numbers, so I lose half of my windows (and causes the list to be interspersed with zeroes; these are the upper 32 bits of each number).
