To make things even worse... (allright, I will try ARMGNU 4.1.1 or give up, and
use copy-paste)

typedef unsigned uint;
//##################################################################################################
struct Now {
        static volatile uint centi;
        static uint synced;
        static uint seconds; }
now;
//##################################################################################################
template<typename TIME, const volatile TIME& NOW>
  class TTimer {
public:
        TIME from;
public:
        void start() {
                from = NOW; }
        TIME elapsed() {
                return NOW - from; }
        bool reached(TIME timeout) {
                return NOW - from >= timeout; }
        void fire(TIME timeout) {
                from = NOW - timeout; }};
//##################################################################################################
typedef TTimer  <uint, now.centi>       Timer;
typedef TTimer  <uint, now.synced>      CsTimer;
typedef TTimer  <uint, now.seconds>     SecTimer;
//##################################################################################################
int main() {
        Timer timer;
        timer.start();
        while (!timer.reached(100))
                now.centi++;
        return 0; }
