[Python-Dev] Windows compiler for Python 2.6+

I just got bitten by the runtime library incompatibility problem on windows when I tried to load a C extension compiled with MSVC 2005 (64-bit) into Python 2.5. I realize that Python2.5 will continue to use MSVC 2003 for compatibility reasons, but I was curious if any thought had been given to the future of the 2.x series. Cheers, Chris
