Marc-Andre Lemburg:
Changed all references to the MAGIC constant to use a global pyc_magic instead. This global is initially set to MAGIC, but can be changed by the _PyImport_Init() function to provide for special features implemented in the compiler which are settable using command line switches and affect the way PYC files are generated. Currently this change is only done for the -U flag.
