I don't understand the difference between Py_BUILD_CORE and Py_BUILD_CORE_BUILTIN defines. Do we need to have two different defines? Can't we compile _json with Py_BUILD_CORE?

Is it a problem of the visibility/scope of symbols in the python DLL on Windows?

Yep. I added Py_BUILD_CORE_BUILTIN as a workaround for building on Windows. For extension modules on Windows there's a conflict between Py_BUILD_CORE and some of the Windows symbols that get defined. My Windows build knowledge is pretty limited so that's about as far as I can go. :) Steve might be able to give you more info. -eric
