Re: Windows CRT issues with Python 2.6

Hi,

you can use Dependency Walker <http://www.dependencywalker.com/>. If the 
patch is working, pyd files will depend on MSVCR90.DLL, otherwise 
%WINDIR%\winsxs\...\MSVCR90.DLL

There are two issues with Koen's patch (both easy to fix). It does not 
work for 64-bit Python and it also processes exe files build with 
setuptools.
