[Image-SIG] Windows CRT issues with Python 2.6

I've encountered an issue with distributing a Python 2.6 and PIL based
application on Windows computers that do not have the VC 9.0 CRT installed.
The problem is that the _imaging.pyd module fails to load. I believe the
reason is that the file has an embedded manifest specifying the CRT version
to load, which causes it to ignore the CRT files in the Python exe folder.
The pyd files that ship with Python (_socket.pyd, etc..) do not have this
problem because they are built without an embedded manifest, which causes
them to inherit the CRT that is already loaded through the Python process.
You can find information about this at the following bug report (

Would it be possible to modify the PIL build process to not embed a manifest
for Windows pyd files?
