I just came up with an idea how to resolve the VC versioning problems for good: Python should link with mscvrt.dll (which is part of the operating system), not with the CRT that the compiler provides.

To do that, we would need to compile and link with the SDK header files and import libraries, not with the ones that visual studio provides. For that to work, everyone building Python or Python extensions (*) would have to install the Platform SDK (which is available for free, but contains quite a number of bits). Would that be acceptable? Disclaimer: I haven't tried yet whether this would actually work. Regards, Martin (*) For Python extensions, it should be possible to use mingw instead, and configure it for linking against msvcrt.

I think think would remove a lot of headaches. Downloading and installing the Platform SDK should not be an issue, imo.

The only problem that I see is this:

I'm not sure the platform SDK include files (.H and .IDL) are really compatible with VC7.1. I remember that we (on our company, building C++ software) had to 'Unregister the PSDK Directories with Visual Studio' (available from the start menu) before building the stuff, otherwise there were compiler errors.
