Thank you. I have looked at the wrong place.

Let us consider the following code:
[Example:
template <class T>
class A {
public:
 void f();
};

template <class T>
void A<T>::f() {
   0 = 1; // AAAA
   sdfg(); // BBBB
   T::a = 0; // CCCC
}
template <class T>
void g() {
   0 = 1; // DDDD
   sdfg(); // EEEE
   T::a = 0; // FFFF
}

int
main()
{
 A<int> a;
}
-- end example]

Having studied 14.7.1 I have come to a conclusion that the example above
shall be well-formed. But Comeau C++ since 4.2.44 begins to treat AAAA,
BBBB, DDDD and EEEE as errors (all the other compilers I have access to
treat the example above as well-formed).

The question is: does the Standard admits the semantic analysis of
_definitions_ of parameterized functions or member functions which will
never be instantiated? (I believe that all the marked lines above are
syntactically correct.)

Thank you in advance,
with regards,
Michael Kochetkov.
