// Disable printf override in common/forbidden.h to avoid

// which gets messed up by our override mechanism; this could
// be avoided by either changing the PSP SDK to use the equally
// legal and valid
// __attribute__((format(__printf__,1,2)));
// or by refining our printf override to use a varadic macro
// (which then wouldn't be portable, though).
