There is something wrong with the warning about constructor ordering:

wilx@logout:::~/tmp> cat order.cxx
struct A
{ };

struct B
{ };

struct C : public B, public A
{
  C ()
    : A(), B()
  { }
};

wilx@logout:::~/tmp> g++ -Wall -c order.cxx
order.cxx: In constructor `C::C()':
order.cxx:10: warning: base `#`tree_binfo' not supported by dump_type#<type
error>' will be initialized after
order.cxx:10: warning:   base `#`tree_binfo' not supported by dump_type#<type
error>'
order.cxx:9: warning:   when initialized here

wilx@logout:::~/tmp> g++ -v
