/*
* This is a (quite naive) timer, to help determine the speed of various
* functions of Claws. By default START_TIMING() and END_TIMING() are NOPS,
* so that nothing gets printed out. If you change the #if, however, you'll
* be able to get functions timing information. As the implementation is
* naive, START_TIMING("message"); must be present just at the end of a
* declaration block (or compilation would fail with gcc 2.x), and the
* END_TIMING() call must be in the same scope.
