--- Comment #2 from Janne Blomqvist <jb at gcc dot gnu.org> 2011-03-03 17:58:32 UTC ---
>From the code, with line numbers:


 153   /* TODO: How to prevent the compiler warning due to strerror_r of

 154      the untaken branch having the wrong return type?  */

 155   if (__builtin_classify_type (strerror_r (0, buf, 0)) == 5)

 156     {

 157       /* GNU strerror_r()  */

 158       return strerror_r (errnum, buf, buflen);

 159     }

 160   else

 161     {

 162       /* POSIX strerror_r ()  */

 163       strerror_r (errnum, buf, buflen);

 164       return buf;

 165     }


That is, this warning is not an indication of a real problem, as the "wrong"
branch is never taken. Unless somebody has a clever idea how to silence the
compiler warning, I'm planning on closing as WONTFIX.
