Compile error when building against python 3.x

[chrislu]

Since version 1.44 boost python does not compile anymore using python 3.x (after a GSOC project it worked fine with python 3.1).

I tried to build the boost 1.45 official release targeting a x64 version on Visual C++ 2010 under Windows 7 x64 using the following build line:

bjam --build-dir=e:\devel\_ext\boost_out_64\out --libdir=e:\devel\_ext\boost_out_64\lib --includedir=e:\devel\_ext\boost_out_64\inc toolset=msvc-10.0 define=arch:SSE2 address-model=64 link=shared runtime-link=shared -j6 install
bjam --build-dir=e:\devel\_ext\boost_out_64\out --libdir=e:\devel\_ext\boost_out_64\lib --includedir=e:\devel\_ext\boost_out_64\inc toolset=msvc-10.0 define=arch:SSE2 address-model=64 link=static runtime-link=shared -j6 install

These are the errors generated:
