    What is the correct way for a client to determine whether or not the
    (new) base_width, base_height, and win_gravity components are defined
    in the XSizeHints structure returned by a call to XGetWMNormalHints()?

Look at the PBaseSize and PWinGravity bits in the flags.


    Should the client look into the supplied_return argument or into the
    flags component of the XSizeHints?  In what way are these two different?

The sizehints.flags mask indicates which fields are set in the structure.  The
supplied_return argument returns the mask of all possible fields which *could*
have been returned for this property.  New hints will return all of the
possible flag fields, pre-ICCCM hints will not have PBaseSize or PWinGravity
set.
