You could if A were completely unrelated to C.  You have C deriving
from B, and B deriving from A, which means that the name A binds to the
base class inside C; and the base class is inaccessible, so it may not
be referred to.  As Andrew said, use ::A.

If you want chapter and verse from the C++ standard, I can't help you,
but I'm sure someone else here can.
