Hi Ian,

I think the reason is simple: somewhere in Boost tree, or somewhere else, 
there's "import gcc". So "toolset=gcc" works even without explicit "using 
gcc" in user-config.jam.

I think I've cleaned this for Boost, but I've added a todo to look again when 
we start moving Boost to V2.

Thanks,
