I am using a custom Python executable for an application I'm developing. I also build PYDs to extend this Python environment. I decided to upgrade them and my executable to use Visual C++ 10 while the Python DLL and other third party PYDs, specifically wxPython, continued to use Visual C++ 9. Doing this did not cause an issue in and of itself, however, my wxPython release, but not debug, PYDs were failing to load the VC9 CRT.

I discovered this is a result of MSVCCompiler._remove_visual_c_ref() being called in the module disutils.msvc9compiler. I had to comment out this line in order to rebuild wxPython and get my program running correctly.

I'm requesting this feature of the compiler be made optional.

Mark, can you give feedback?

I can't explain why this might be happening given the Python dll is still build against vc9 - I'm guessing this can't be reproduced without vs10 in the mix?

Re making the feature optional - distutils doesn't really lend itself to customizing the compiler best I can tell - the only answer I know of here is to provide your own compiler sub-class and override manifest_get_embed_info to return the manifest filename.
