C++ has the notion of const member function, which is different from what
GCC means by a function attribute const.
Also CV qualifiers applied to function types in C++ is a very delicate
issue -- witness
the myriads attempt/fixes in both the front-end and the standard.
Printing the cv qualifiers
is even more confusing.
