[ros-dev] [ros-diffs] [tkreuzer] 52496: [FAT32] Add some code that does ... nothing, but fixes 2nd stage boot with msvc. To figure out why this is needed, is left as an excercise to the reader :)

[Alex Ionescu]

I know why this is "needed", but this is a temporary hack, right?

Best regards,
Alex Ionescu
