XK_Num_Lock lives in X11/keysymdef.h. I think it is usual to
#include <X11/keysym.h>, which in turn includes keysymdef.h.

It seems that gdk/gdkkeysyms-update.pl looks for keysymdef.h among
others, and attempts to make a gdkkeysyms.h from it?

Looking at gdkkeysyms.h, GDK_KEY_Num_Lock = 0xff7f matches XK_Num_Lock
which is also 0xff7f.

So, to cut a long story short, the attached (untested) patch, should
do the trick.

Cheers,

Patrick
