Message        "restrict" is a keyword in the C99 revision of the C
                standard.  Using it as an identifier will prevent
                your program from conforming to that standard.

 Description    The token restrict has been selected as a keyword in
                the C99 release of the C standard.  Because the
                program uses it as an identifier, the program will
                not conform to that standard.

 User Action    Change the name of the identifier.
