Yes it does.  Can you try this test:
In the file kdelibs/kdecore/kxerrorhandler.h, insert the following line:

#include <tqevent.h>

directly before this block of text:

#include <tqvaluelist.h>
#include <tqwindowdefs.h>
#include <kdelibs_export.h>
#include <X11/Xlib.h>

Retry the compilation; if it gets farther please let me know.
