Deriving into different namespaces

Thanks for your bug report. Unfortunately, I cannot reproduce the
problem; please read

http://egcs.cygnus.com/faq.html#bugreport

and provide more details. I've been trying the code

class Base{};
namespace A {
class derived1: public Base {
};
}

int main()
{
  A::derived1 *x;
  static_cast<Base*>(x);
}

and it compiles fine for me.

Regards,
Martin
