>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.
