-Werror=strict-prototypes is too strict IMO. It will even break:
int test() { return 0; }
But the entire point of the C2X change about the prototype w/o a
parameter list is to make such thing reasonable, isn't it?
I guess we actually want a new warning option, like:
extern int f(); // ok
int g() { return f(); } // ok
int h() { return f(1, 2); } // { dg-warning "the usage of non-strict prototype will be rejected by C2x" }
