    Use %jd and %ju instead of PRIdMAX and PRIuMAX.
    
    The problem is that on Windows PRI[du]MAX expands to a
    Windows-specific printf flag, but we are using printf wrappers, which
    do not understand that flag. The 'j' flag on the other hand, is not
    supported by Windows, but *is* supported by our wrapper, so it's safe
    to use.
    
    One notable exception from in the commit is a scanf which uses
    PRIdMAX. scanf is not covered by our wrappers at the moment, and has
    no replacement, so we need to leave that as it is. sprintf is not
    covered either, but can (and should) be replaced with snprintf.

    Disable printf format warnings on Windows.
    
    Our wrapper supports more flags than vanilla Windows version, so they
    are false positives.
