[Boost-users] [1.34] autolink doesn't work when not specifying toolset version

I downloaded 1.34.0 beta, compiled it using bjam --toolset=msvc --without-python stage then wrote a small program that uses Boost.Thread. It didn't link. The linker was looking for libboost_thread-vc80-mt-gd-1_34.lib, but couldn't find it. Rightfully enough, because there was no such file. The bjam command created libboost_thread-vc-mt-gd-1_34.lib - almost the same, just "vc" instead of "vc80". So I ran bjam again, this time with bjam --toolset=msvc-8.0 --without-python stage and then everything worked fine. This can a be a bug either in Boost.Build, or in the autolink feature, or in the documentation (getting_started.html) that suggests that specifying the toolset version is optional, or in my brain... Which is it?
