agreed.

I don't think it's going away any time soon. For example, it's the only
platform I've been able to make work on my Vista box, and nobody has
told me how to get around the problems, even though apparently some have
managed to make MSVC work on Vista.

This is the least good option IMNSHO.

Yes, I can live with this one too, although I don't think option 2 is so
bad either.
