Seems like a bug introduced by an invalid merge op,
changing the head of qtbrowserplugin_p.h like the following:

#ifdef Q_WS_X11

class QtNPStream;
class QtNPBindable;
#endif

<<<<<<<<<< new <<<<<<<<<<<<

#ifdef Q_WS_X11
#   include <X11/Xlib.h>
#endif

class QtNPStream;
class QtNPBindable;

fixes this issue.

I cannot reproduce this - it works for me.
