Why? It's admittedly rare, but it's legal to have a definition for a pure
virtual function, and then it can also be inlined. The warning is just as
useful (or not useful, IMHO) as for any other function.

struct X {
virtual inline void f() = 0;
};
struct Y : X {
virtual void f () {
X::f ();
}
};

tmp/gg> gcc -c x.cc -Winline
x.cc:2: warning: inline function `virtual void X::f()' used but never defined
