I apologize if my extra PR is causing confusion.  My original intention was to merely forward port Antoine changes so they could compile with the 'master' version of Python.  Over time I have made some fixes to it.  I have kept it open because I'm not sure which approach is better (JSR or duplication).

I did a quick test on the .pyc code size increase.  It is actually tiny for the Python code in Lib/.
