- Mostly this cleans up the #includes and header files in the python project. - Warning fixes are mostly casting issues and misc fixes. General warning clean up. - #include Python.h MUST come as the first include to avoid the POSIX redefine warning in the unix makefiles - fno-strict-aliasing flag added to makefile to fix a unavoidable type punning warning in types.c
