WCHARCAT

Message        A character string literal was concatenated with a
               wide string literal.

Description    The C99 standard defines the behavior of adjacent
               string concatenation between character string
               literals and wide string literals, basically
               promoting the character string to a wide string
               before forming the wide string result.  The older C90
               standard gave this construct undefined behavior - it
               only defined concatenation between adjacent strings
               of the same kind (all character or all wide).
               Although this version of HP C always gives the C99
               behavior with diagnostics optional, some compilers
               (including previous versions of HP C) may give more
               severe diagnostics and/or different behaviors.
