Subject: [PATCH 1/3] Made the timestamper use timeGetTime() instead of
 GetTickCount() on windows since timeGetTime() is more accurate.

         <p>
             The commands for gcc on windows are the same as above but you may also have to link 
-            (via the -l option) to the following libraries: gdi32, comctl32, user32, ws2_32, or imm32.

             However, it's worth pointing out that Visual Studio Express is free and a much better choice for
             windows development than gcc.
