Although not incorrect, using 32768L or 32768U is not necessary. 
According to section 7.11.1 of Harbison and Steele:

    Preprocessor constant expressions must be evaluated at compile
    time, and are subject to some relatively strict constraints.  Such
    expressions must have integral type, and can involve only integer
    constants, character constants, and the special defined operator. 
    All arithmetic is to be done using types long or unsigned long, as
    appropriate to the signedness of the operands, which frees the
    preprocessor from having to deal with several sizes of integer
    types.
