Message 241868 - Python tracker

I'm working on a new version of Georg's patch which applies to the current default branch.

I'm having trouble with AC output going into a separate file, since this requires a lot of things to be declared before the #include of the .c.h file. Should I move all of those definitions to the top of the file, even if they are currently spread all over it? Should I just add forward declarations? And if the latter, how do I forward-declare a struct typedef?
