This directory contains the Haskell->CLX support code. If you see errors like "ID 42 is a :WM_RESIZE_HINTS, not a window", you can get rid of them by loading clx-patch.lisp. This seems to be a bug where CLX is not consistent with the protocol in some way; we've seen it on some machines and not others. The line (load "$HASKELL/progs/lib/X11/clx-patch.lisp") can be placed in your .yhaskell file to load the patch on startup.
