Change what language? C++?
Well it is part of the C++ standard.
6.6.3/2:
A return statement with an expression of type "cv void" can be used only in
functions with a return type of cv void; the expression is evaluated just
before the function returns to its caller.


Which means:

int f(void);

void g(void)
{
  return (void)f();
}

is also valid.

So the warning is useless as this is explicated in the C++ standard.
