Does it work if you don't use gdb?

Maybe the xlib unit links against a library that defines those symbols
as weak symbols. This would mean that if no other code defines those
symbols, the versions from that library will be used, and otherwise the
versions from the other code (and you won't get duplicate symbol errors
due to the weak nature).
