>Description:
GCC rejects code similar to 14.5.2 [#2] as follows:

[gbeauchesne@thalys vrac]$ g++ member2.C
member2.C:8: template definition of non-template `void A::f()'
member2.C:9: redefinition of `void A::f()'
member2.C:8: `void A::f()' previously defined here
member2.C:9: no `void A::f()' member function declared in class `A'

Reproduced on at least GCC 3.2.X and GCC 3.3 CVS snapshot from 2003/02/05.
>How-To-Repeat:
/* { dg-do compile } */

struct A {
  template<class T> void f();
  void f();
};

template<class T> void A::f() { }
void A::f() { }

struct B {
  template<class T> void f() { }
  void f() { }
};

int main()
{
  A a;
  a.f();
  a.f<int>();
  B b;
  b.f();
  b.f<int>();
}
>Fix:
Workaround: define A::f<T>() and A::f() both inline, as exercised in class B.

Both ICC and Comeau C++ compile this correctly. But this is not a fix. ;-)
