>From SF #607253, header file problems ( http://python.org/sf/607253 ) is there any reason why these files: graminit.h patchlevel.h pyconfig.h (aka pyconfig.h.in) don't protect against being included multiple times? ie, they don't have: #ifndef Py_FILE_H #define Py_FILE_H /* ... */ #endif /* !Py_FILE_H */ Neal
