    [FASTFAT_NEW] "Fix" Flags bitfield to avoid RTC error
    
    Since VS 16.11 the compiler sometimes emits calls to _RTC_UninitUse, when parts of a
bitfield are initialized (See
https://developercommunity.visualstudio.com/t/Broken-runtime-checks-with-CL…).
Fix this by using an ULONG instead of a bitfield.
    Note: The structure uses a 24 bit bitfield plus an UCHAR, which is supposed to form a
32 bit field, but that doesn't work anyway.
