Ah. I didn't know about that. I'm still learning about BB. :-)

I think the default should be prepending "lib" on Unix, since that's
what most (all?) linkers look for when you give it "-lfoobar". I agree
(now that I know about it) that for the <tag>@some_rule form, it should
not be done, though.
On a side note, I'd like to express my thanks to the developers --
Boost.Build V2 is solving a lot of the build problems that have been
driving me crazy over the years. Keep up the good work!
