From the Intrinsics manual, "The resource_size field is the size of
the physical representation in bytes; you should specify it as
"sizeof(type)" so that the compiler fills in the value."

Therefore, you should instead have:

         {"landscape", XtCOrientation, XtRBoolean, sizeof(Boolean),
                  (Cardinal)&landscape, XtRBoolean, (caddr_t)&true},

The difference in sizes between Boolean, typedef'd to char, and int
varies among machines and this probably made things work under Ultrix
but not on your Sun.
