* cccp.c: Don't define HOST_WIDE_INT.  Replace all occurrences of
        WIDE_INT with WIDEST_INT.
        * cexp.y: Likewise.
        Don't define unsigned_HOST_WIDE_INT, CHAR_BIT or
        HOST_BITS_PER_WIDE_INT.  Replace occurrences of PRINTF_PROTO_1()
        style with PVPROTO() ATTRIBUTE_PRINTF_1 style macros.  Replace
        occurrences of "unsigned_HOST" with "unsigned HOST".  Provide a
        definition of variable `c89' when compiling a test binary and set it.
        * system.h: Don't define the PRINTF_PROTO_* macros.
