I've done so, thanks for pointing the discussion.

In the meantime, I've just patched distutils/msvc9compiler.py so that it 
neither embed nor create a manifest assembly. This way, I'll be sure 
that the assembly information would be fetched from the main python (or 
python-based) binaries (i.e. pythonX.dll). That may be a very strong 
prerequisites in some cases, but never in my very particular case.
