Well, actually when you build anything that depends on boost with v2.
This is due to the fact that Boost-Toplevel Jamfile.v2 has use-project rules
for _all_ non-header-only libraries. So V2 parses and checks these projects.
This bites me, too, because I use _none_ of those libraries...

Yes. These warnings should only appear when the stated libraries are actually
Now, they are issued when these libraries are onle _referenced_ by some
Jamfile which happens to have "use-project /boost $BOOT_ROOT" in it...
