AFAIR, it's not the default, so most if not all distributions include it as
a binary. Is the header-only version equivalent to the compiled one?

No, Boost.System is also used by Boost.Filesystem and Boost.ASIO, which I
also use. And I probably catch and throw Boost.System exceptions somewhere
in my code as well.

Ok, I will create a Trac ticket then and see what I can do.
