Subject: [PATCH] Re-define PRI?64 for mingw. The reason is that mingw does not
 recognize %I64? as 64 bit formats but assumes integer formats and warngs
 about int64_t arguments. The mxmsg functions already convert %ll? etc into
 the proper %I64? values on Windows, so I can use %ll? just to shut up mingw.
