annotate Python/compile.c @ 28325:850626d47574 legacy-trunk

Fixed SF bug #663074. The codec system was using global static variables to store internal data. As a result, any atempts to use the unicode system with multiple active interpreters, or successive interpreter executions, would fail. Now that information is stored into members of the PyInterpreterState structure.
