The headers generated by gcjh are incorrect when a namespace

extern "Java"
{
  namespace A
  {
    namespace B
      {
        class ClassA;
      };
  };
  namespace C
  {
    namespace A
    {
      class ClassB;
    };
  };
};

class A::B::ClassA
{
};

class C::A::ClassB : public A::B::ClassA
{
};
>Fix:
Prefix any namespace with a duplicate with ::.

    Can you try it out?  If so, please do and get back to me.
    If not, tell me and I will just close this PR.

 Hmm.

 Prepending to all of them.
 
 Can you try gcjh on the .class files in libgcj and see if it works
 there?

 My gcjh generates decls with "::java::lang::Object *", which leads me
 to suspect that you're still picking up the wrong gcjh.

 That was the case.  Sorry about that and thanks for the fix.
