I don't have up-to-date V2 tests there, but some time ago they looked OK.

Any ideas why those options are needed? And what they do? Especially the 
first? I'd rather figure out what's going on there and add a relevant test.

I wish I new. At least on Unix, V1 has exactly the same behaviour -- the 
version is both in name and in suffix. I just copied it over.

bjam --v2 link-runtime=static

is the right spelling. Do you have a link to the doc which has the wrong one?

I think the above command should do what you're asking for.
