So far the only failure that's been seen is in Numpy 23.6 (23.1 works), and it works with a different version of one of the packages. Was very pleased when I just typed "vc7" and was able to move both packages to Python 2.4 just by running setup.py again (having just finished building them for Python 2.3).

I tested with the patched version of PyGreSQL (it uses the strtoll function, so fails to compile on VC6, don't know if it would work under VC7 without the change), btw.
