For the record, if anyone (including me) needs this info: I checked,
and python 2.5.2 on amd64 is indeed build by a compiler reporting MSC
1400 (VS 2005 serie). I don't think VS 2003 compiler is used at all,
actually - maybe the VS 2003 IDE can be set to use the SDK compilers,
though.

cheers,

David
