   > My recommendation is that you do not go in this direction. It is not standard and totally inappropriate for used in a standards-based OS.

   Ok, I remove getopt_r from patch, since it's a seldom used feature, the compatiblity isn't a big problem without it. But, many application use getopt_long and TLS can't help here.
