You're missing a semicolon here (and also is some other
places at the end of declarations of classes).

This is the place my compiler doesn't like when other,
minor issues are fixed:

  error: no matching function for call to ‘B<A>::B()’
  note: candidates are: B<Z>::B(const char*) [with Z = A]
  note:                 B<A>::B(const B<A>&)

Shouldn't that be 

template< class A, template < typename > class B >
C< A, B > :: C( const char * msg )
  : B< A >( msg )

since B<A> is the base class C is derived from?

Otherwise I guess the compiler will try to invoke the
default constructor of B<A> (since there's no explicit
call of it - you call B(msg), not B<A>(msg)) and since
there is none it gives up.
