Martin has uploaded a patch which modifies the Python API level number depending on the setting of the compile time option for internal Unicode width (UCS-2/UCS-4): https://sourceforge.net/tracker/?func=detail&aid=445717&group_id=5470&atid=305470 I am not sure whether this is the right way to approach this problem, though, since it affects all extensions -- not only ones using Unicode. If at all possible, I'd prefer some other means to handle this situation (extension developers are certainly not going to start shipping binaries for narrow and wide Python versions if their extension does not happen to use Unicode). Any ideas ?
