well, "--toolset=" is wrong, should be "toolset=". But this does not matter if 
youhave only one msvc installed...

The main point might be step 7 from  you build instructions:
7. Create empty jamroot file in C:\boost\libs\gil
        - needs to be removed when building gil's unit tests

This jamroot will prevent Boost.Build from picking up Boost's own Jamroot in 
c:\boost which has the necessary magic to force multithreaded builds on 
msvc-8.0 and up.

And then only the autolink magiv does its work, as Volodya has already 
detected:

Please put an empty "Jamfile" in libs\gil and it just running "bjam" might 
work.
And please try running "bootstrap.bat" instead of the manual configuration 
steps for bjam in your instruction. Should work better.

Yours,
