>Description:
Even with -Wreturn-type the compiler does not warn
when no return value is supplied,
see the following example (only 3 lines of code):

---- test.C begin ----
#include <string>
int f(string) {}
int g(const string &) {}
---- test.C end ---

> g++ -c -Wreturn-type test.C
test.C: In function `int g(const string &)':
test.C:3: warning: control reaches end of non-void function `g(const string &)'

The compiler warns about function g, but there is no
warning about function f.
