>Description:
GCC 3.2 can't compile the test-case overload.cpp listed in How-To-Repeat. Alexandrescu's loki-lib contains code like that (MultiMethods.h/FnDispatcher::Add()), so it can't be compiled either.

g++ overload.cpp

overload.cpp:5: `template<class T, bool flag> void A::f()' and `template<class T> void A::f()' cannot be overloaded
overload.cpp: In function `int main()':
overload.cpp:11: no matching function for call to `A::f()'
>How-To-Repeat:
// file overload.cpp

struct A {
	template <typename T>           void f() { }
	template<typename T, bool flag> void f() { }
};

int main() {
	A a;
	a.f<int>();
	a.f<int, true>();
}
