What do you have in your user-config.jam ?

Try setting it up like:

using msvc : 10.0 ;
using msvc : 9.0 ;
using msvc : 8.0 ;

(i've got 8.0 and 9.0 in mine, but it's been ages since i set it up and i don't
recall all the details)
.
 
All I have in my user-config.jam is some stuff to work with different python version, no msvc lines. Aside from running regression tests, I can build fine with just b2 toolset=msvc-8.0(or another)....and have never needed anything in my user-config.jam for this.  Are the regression tests that start from run.py different from this?  

I'll give the user-config.jam stuff a try after I test removing the other env variables.
