Thanks. Yes I am aware of that fact. It is just a matter of
understanding the implications of having a different name mangling for
C++ and Java. This also means that another c++ compiler won't be able to
 use a gcjh generated header to link against a Java so.
Is there a plan to add return types to the C++ name mangling in general?
(anybody aware of such a change for C++0x?)

Yes. I was just wondering, why java::lang::Object is not declared as
extern "Java" in libjava/java/lang/Object.h. Aha but aparently there may
be a forward declaration like in the Foo case below.

Thanks.
