GCC mis-compiles the following code for mysterious reasons. While it should
output "called", it outputs nothing at all
// snip
typedef void Fn() const;
struct Foo { Fn fn; };
void Foo::fn() const { std::cout << "called" << std::endl; }
int main() { Foo f; f.fn(); }
// snap
Any one of the following makes it show "called" properly:
- Adding "inline" function specifier in the declaration of the function at
class or namespace scope.
- Replacing "Fn fn;" by a declaration with a function declarator "void fn()
const;"
- Making the function non-const (in the typedef and in the definition of the
function).

Also fails with g++-4.0.1 and g++-4.2.1 (i686-darwin10).
g++-3.4.6 rejects the example:
error: invalid type qualifier for non-member function type
