 All of the gcc compliers I tried fails and produces a message of (gcc 
 version 3.1 20020114 (experimental), gcc version 3.0.4 20011213 
 (prerelease))
 
 cccTestTempletePrivate.cc: In method `int A<T>::f () [with T = B]':
 cccTestTempletePrivate.cc:14:   instantiated from here
 cccTestTempletePrivate.cc:8: `int B::i' is private
 cccTestTempletePrivate.cc:3: within this context
 
 
 or of(gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) :
 
 cccTestTempletePrivate.cc: In method `int A<B>::f<B>()':
 cccTestTempletePrivate.cc:14:   instantiated from here
 cccTestTempletePrivate.cc:3: member `i' is a private member of class `B'
 
 so even the redhat compiler (gcc version 2.96 20000731 (Red Hat Linux 
 7.1 2.96-85)) complains with
 
 cccTestTempletePrivate.cc: In method `int A<T>::f () [with T = B]':
 cccTestTempletePrivate.cc:14:   instantiated from here
 cccTestTempletePrivate.cc:8: `int B::i' is private
 cccTestTempletePrivate.cc:3: within this context
 
 
 So please close this report since this was never a problem.
 
 Thanks,
 Andrew Pinski
