It's going to be included in the next major Boost release (1.31, presumably
a couple months away). Meanwhile, you can get the latest version of it from
the Boost CVS repository - http://www.boost.org/more/download.html#CVS

On which compiler? Anyway, I beleive things have much improved since then -

Not in Boost (unless you are interested in the special case covered by
Optional library - http://www.boost.org/libs/optional/doc/optional.html).
Personally, I am not aware if any other discriminated union library that
would be as powerfull and well-engineered as Boost.Variant.
