// Fallback for console/addon platforms (e.g. POLYPHASE_PLATFORM_ADDON targets
// like PSP) that don't have their own #elif arm. Without these, every
// `#if INPUT_GAMEPAD_SUPPORT` in the engine silently compiles to false —
// most notably the `memcpy(mPrevGamepads, mGamepads, ...)` in
// InputUtils::InputAdvanceFrame, which means mPrevGamepads stays all-zeros
// forever and IsGamepadButtonJustDown returns TRUE every frame the button
// is held. Symptom on PSP: a single d-pad press cascades through 2-3 Button
// widget nav steps because each held frame re-fires the JustDown edge.
//
// Console default: gamepad only (no keyboard / mouse / touch hardware on
// PSP, GameCube, etc.). Touch-capable consoles (Wii IR, 3DS, Vita)
// override to 1 in their own #elif arm above.
//
// #ifndef guards: an addon platform whose hardware differs from the console
// default (e.g. the Web target, which has keyboard/mouse/touch) can pass
// -DINPUT_*_SUPPORT=1 on its compile line and win over these fallbacks.
