commit e7c493bdd3ca642d849a194bf46d00c07cfe8180

    Fix a lot of warnings like "warning: this decimal constant is unsigned only in ISO C90".
    
    In C89/90 an unsuffixed decimal constant must be interpreted
    as int, long or unsigned long (whichever fits first).
    In C99 it must be interpreted as int, long or long long
    (whichever fits first).
