When an older GCC version is called with a too new warning option, GCC exited with an error and Asterisk was not built. Therefore, the configure script tests the installed compiler whether it supports that warning option. If not, Asterisk does not pass it to the installed compiler. However, some compilers (like clang) do not exit (error) but give just a warning in such a case. Because the compiler did not exit, Asterisk passed the unknown-warning option.
