[Boost-build] [v2] Can't build python extensions under windows

Hi
I am trying to build Boost.Python examples (getting_started1 and 2) under
windows with BBv2

I tried 1.33.0, 1.33.1beta and lattest version of boost-build from cvs (though 
I still use released version of boost, 1.33.1beta) and all I achieved is some
variation in bjam's error reports.

Here's a piece of bjam output:

% bjam --v2 msvc-7.1

msvc.link.dll bin\msvc-7.1\debug\getting_started2.so
bin\msvc-7.1\debug\getting_started2.lib
   Creating library bin\msvc-7.1\debug\getting_started2.lib and object

Why "subsystem:console"? why ".so"?

user-config.jam:
using python : 2.4 : "D:/Program Files/Python241" ;
using gcc ;
using msvc : 8.0 : "D:/VisualStudio8/VC/bin/cl.exe" ;
using msvc : 7.1 : "D:/VisualStudio.NET2003/VC7/bin/cl.exe" ;

jamfile (unchanged):
project : requirements <library>/boost/python//boost_python ;   
python-extension getting_started1 : getting_started1.cpp ;
python-extension getting_started2 : getting_started2.cpp ;

project-root.jam:
path-constant BOOST_ROOT : D:/denis/code/boost_1_33_1 ;
use-project /boost : $(BOOST_ROOT) ;

There are some other issues:
1. Unusual big ammount of warnings in Boost.Python headers (with lattest
boost-build only)
2. bjam rebuilds everything from scratch all the time

Is it my problem or Boost.Python supposed to work with v1 only?

Thank you for your attention!
