Well, my patch seems to have fixed your previous compile error so I
think it is good.  The errors above are unrelated to the patch.

The errors above indicate that the symbols XK_Alt_L XK_1 and XK_9 are
undefined.  (I don't understand where the weird 'â' characters are
coming from in the error report above).

These symbols should be defined in /usr/include/X11/keysymdef.h which is
included by vnc.c.

Please check that you have this header file installed on your build
machine and that the symbols are defined in it.

Harry.
