The docs are wrong ;-) The <source> feature is identical to putting something
to the list of sources. The <library> feature is almost the same, but only for 
linking. So, <library> feature on a target that does no linking is ignored.

Wierd. Can you compare the link lines. The only reason I can think of is that 
in one of the cases you don't link to boost.filesystem at all, and mingw for
some reason don't report unresolved symbols.

IIRC, we had similar bug a long time ago -- where gcc would produce executable 
with unresolved symbols without a warning. Maybe, mingw is somewhat specific
in this regard.
