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