   Since we changed the return value of getxxx_r, I added a new version
   for each function and kept the old one.

I think you should also set errno since the new functions do not
necessarily do this.  The whole point of having getXXbyYY_r returning
the error value is avoiding the use of thread-specific data.

So instead of:

   if (ret != 0)
     ret = -1;

we should use

   if (ret != 0)
     {
       __set_errno (ret);
       ret = -1;
     }
