One can't just #undef errno on windows because it is defined as follows: #if defined(_MT) || defined(_DLL)extern int * __cdecl _errno(void);#define errno (*_errno())#else /* ndef _MT && ndef _DLL*/extern int errno;#endif /* _MT || _DLL */ So when building a dll or a multithreaded application it is not a plain variable but call to the _errno() and after #undef errno one will lose errno completely. For the same reason it is impossible to use something like 'errno=0;'.
