The Athena widget set include files were placed in a directory separate
from the Xt Intrinsics in order to emphasize the distinction between them,
and to avoid naming collisions and to distinguish between the Athena 
widget set and other widget sets.

Code written to R3 and prior expects the links to exist, but code written
now should not expect these links to exist.  The older code should be
changed as part of its maintenance.  This is important: in future releases
of the Athena widget set, it cannot be assumed that the same support for
backward compatibility will be present.  For a guide to the changes
needed, see doc/Xaw/ConvertToR4.

No, not in the Athena widget set; but see section 13.1 of the R4 Xt doc.
