re PR c++/16190 (-Wnon-virtual-dtor, in -Wall, silenced only by pessimizing code)
PR c++/16190
* c-opts.c (c_common_handle_option): Don't include
-Wnon-virtual-dtor in -Wall; enable if -Weffc++.
* doc/invoke.texi (C++ Dialect Options): Document that
-Wnon-virtual-dtor is no longer included in -Wall.
