Wow! Weird :-\

That would be the "flavor" feature being injected to distinguish the 
MinGW specific GCC version.

Just treat it as a regular Unix gcc:

   using gcc : : /path/to/g++

And build with:

   bjam gcc

If you also had the MinGW version set up you could:

   bjam toolset=gcc,gcc-mingw

That would be me... But I must confess, I just dread having to edit the 
BBv2 BoostBook documentation files. I have no clue where to put things 
and writing docs in XML is among the most painful tasks I can think of.
