First round of VAX patches. This isn't complete right now, there are for
sure still bugs (properly hidden, of course), a libm is completely missing (I've got one that implements some basic stuff, but that's really not ready for checking in...) I've also got a list of other things that need touch-ups, but that's mostly minor stuff that'll be done during the next days.
