Marcin Cieslak 1041e08003 Fix dtfile crash on 64 bit 
When asking for data using XtVaGetValue()
make sure that there is enough place for
the return value (which is sometimes XtPointer).
Providing pointer to (int) is not enough.

Cast XtPointer into requested int types
directly, which unfortunately introduces
compilation warning:

cast from pointer to integer of different size
