Thanks, I'll simplify that part to:

bool
file_accessible_directory_p (char const *file)
{
#ifdef DOS_NT
  /* There's no need to test whether FILE is searchable, as the
     searchable/executable bit is invented on DOS_NT platforms.  */
  return file_directory_p (file);
#else
  ... same as before ...
#endif
}
