it looks good. i had a few problems compiling out of the box
on my platform (linux):

  in drawstuff:
    x11.cpp: In function `void createMainWindow (int, int)':
    x11.cpp:146: `strlen' undeclared (first use this function)

  in ode:
    timer.cpp: In function `void dTimerReport (FILE *, int)':
    timer.cpp:331: `strlen' undeclared (first use this function)

must be just a missing include or something. anyway, there are some
other things we'll need to configure too:
  * HUGE_VAL should be the maximum representable dReal. this is
    normally infinity. HUGE_VAL is poorly defined right now.
    on many systems infinity is 1.0/0.0 - but not all?
  * high resolution timer functions in timer.cpp. these are not
    needed for normal operation, but are a must for testing.
