When we discussed VC versions (back when we met in Ofxord during PythonUK/ACCU), David Abrahams seemed adamant that VC7 and VC6 are indeed compatible

I doubt he said this in this generality: he surely knows that you cannot mix C++ objects files on the object file level between those compilers, as they implement completely different ABIs.

For Python, the biggest problem is that you cannot pass FILE* from one C library to the other, because of some stupid locking test in the C library. This does cause crashes when you try to use Python extension modules compiled with the wrong compiler.

And not the only problem. Review the "PyObject_New vs PyObject_NEW" thread from python-dev in March. This snippet sums it up:
