int overridable (int v) { return (v); }
template <typename T>
int call_override (const T& v) { return (overridable (v)); }
int overridable (float) { return (1); }
int main (void)
{
return (call_override (0.0f));
}
-------------------------------------------------------------
The above code compiles fine with 4.0.2, but does not work with 4.2.0 20070207,
where call_override does not see the float version of overridable even though
it is available at the time of instantiation.
I use this method in my library to allow overriding a function for
user-specific types.
