To build *Python extensions*, one can use Carl's toolchain or the VC9
compiler for Python 2.7 that Microsoft just released.

To build *Python* you need Visual Studio, Visual Studio Express, Windows
SDK, or Cygwin because there is no other build process available on
Windows. Python cannot be built with MinGW.

The official 64-bit Python installer from Python.org is built with the
Windows SDK compiler, not Visual Studio. The Windows SDK is a free
download. The 32-bit installer is built with Visual Studio.
