Yeah, I was having build problems last night too. Seems to be building fine
again just now.

Your test case gives an internal compiler error trying to instantiate
java::lang::Object. I changed it a bit and now have something that gives the
same error that we're seeing in libgcj:

// Test java booleans and overloading

extern "Java"
{
  typedef __java_boolean jboolean;
  typedef __java_int jint;
  typedef __java_short jshort;

  namespace java
    {
      namespace lang
        {
          class Object;
          class Class;
        };
    };

  class Bar
  {
    Bar (jboolean b);
    Bar (jshort j);
  };
};

typedef class java::lang::Object* jobject;
typedef class java::lang::Class* jclass;
extern "C" jobject _Jv_AllocObject (jclass, jint);

class foo
{
  Bar *x;

  foo ()
    {
      x = new Bar (false);
      x = new Bar (21);
    }
};

[bryce@reason overload]$ gcc test.cc
