Because the NetBSD bootblock compiles w/o the AmigaOS NDK/SDK or whatever it's called this week, and they implemented part of the headers that is absolutely needed. Therefore struct Window is not available, so you can't sizeof it. So the comment just explains what that magic number actually is.

I mean, I technically could have declared a 136 byte dummy struct as Window, and sizeof it, but ... It's messy either way. Pick your poison.

I see, well done.
