There's currently a compile error in trunk when multi-threading is enabled.
However, I think the root cause of the problem is that there's currently too
many compile flags so developers can't test the different combinations.
Specifically, the boost library and multi-threading options.

I've made a little poll to to see if people want to make Boost library a
prerequisite, and threading always turned on:

The poll also asks if you're willing to chip in and help out whichever way
you vote.

Having Boost only as an option makes it difficult to develop in Moses and
makes it error prone, as we see with the compile error.

Mandating Boost may mean some people have to install the correct Boost
version on their machine. There may be Boost questions on this mailing list
as a result.

ps. the compile error is
