	The function void f(Base& b) in the following program caused an error
if I used the Sun C++ 2.0 translator as follows:

""prot.cc", line 18: error:  Derived::f() cannot access Base::a: protected
member 

Howerver, g++-1.34.2 on the Sun3 OS 4.0.1 did not produce any error.  Which
behavior is correct? (I think this is a 1.34.2 bug...)  This g++ behavior is
different from the g++-1.36.x?

Thanks in advance,
