The mingw patch for fixing this Vista regression (from Danny Smith on
March 5th) is in mingw-runtime-3.12-1. It is in file <include/io.h> and
works like this:
#ifdef __USE_MINGW_ACCESS
/* Old versions of MSVCRT access() just ignored X_OK, while the version
shipped with Vista, returns an error code. This will restore the
old behaviour */
static inline int __mingw_access (const char* __fname, int __mode)
{ return _access (__fname, __mode & ~X_OK); }
#define access(__f,__m) __mingw_access (__f, __m)
#endif
Whenever the X_OK bit is set in the mode flag for access(2) Vista
returns an error for the call. So yes, using __USE_MINGW_ACCESS will not
work on older mingw versions. Defining X_OK to 0 for mingw might fix the
problem for older versions.
