Absolutely. I use it mostly because of the IDE, though. :) It lets me use
the MSVC IDE, which I think works quite well.

Yes. You'd need a 100% non-Microsoft extensions library, if using this
option, from what I found.

Anyway, like I said in the posting before that one, I haven't had a chance
to test out the options, to find out which combination of options is needed,
to compile things like the BLL. Therefore, I said that as a starting point,
one could try this option. I did not say that this necessarily works as is.

In what way do you mean publish results?

When it comes to configuring Boost for a compiler (with config.hpp), I guess
it could assume a certain setting of the options, that work best across
Boost. In that case, these options could well be published, so that people
know how to configure their compiler for Boost.

Have you tried this setting with the BLL examples, as well?
