In general that's not true; you only get in trouble if you use the
pointers in such a way that the linker can't tell if you're trying to
be recursive or not (function pointers calling functions that call
through function pointers).  I've never run across that limitation in
real-world usage of using multiple pointers pointing at functions with
not just the same signature, but the same type.
