error: Python was built with version 7.1 of Visual Studio, and extensions need to be built with the same version of the compiler, but it isn't installed.

So even though I have the free VC7 compiler, and it's in my PATH, I still can't build a simple extension with it.

Of course it won't. You need VC7.1, which comes as part of Visual Studio .NET 2003.

I suspect it's possible, but non-trivial, to get it working. I'm not sure I understand distutils well enough to risk attempting to get it right :-(

I doubt it could work, in the general case. VC7 uses msvcr7.dll, whereas VC7.1 uses msvcr71.dll. Mixing different versions of the C runtime is not supported by Microsoft.
