required. * errno.cc: Use DWORD to hold Windows errors. (geterrno_from_win_error): New function. (seterrno_from_win_error): Use geterrno_from_win_error to convert supplied windows error (suggested by Corinna Vinschen). * path.cc (symlink_info): Add error element. * path.cc (path_conv::check): Remove errno setting. Use new symlink_info errno element to set path_conv error, where appropriate. (symlink_info::check): Set error element rather than attempting to manipulate errno. Add more checks for trailing / and /.. even though they are currently useless. Avoid setting EINVAL. * path.cc (normalize_posix_path): Correct check for trailing /.
