I've settled on replacing x << n with x * (1 << n); this gets rid of the "left shift of negative value" warning, but will still trigger undefined behavior if the multiplication overflows. It also still looks like a left shift, which is good for the readability of the fixed-point code. (The compiler is smart enough to recognize that the multiplication+shift is just a shift, for both variable and constant shift amounts, so the generated code should not change.)
