So the problem is that ioDevices is defined in js.h and
in jsMacOSX.cxx as

   io_object_t jsJoystick::ioDevices[kNumDevices];

...but static objects need to have their size known at
compile time - and anything that #include's js.h can't
know the value of kNumDevices - even though it's a 'const'.

I think we need to add into js.h something like:

#define JS_MAX_OSX_DEVICES  32

...and replace the kNumDevices line in jsMacOSX.cxx with:

   int jsJoystick::kNumDevices = JS_MAX_OSX_DEVICES ;

...and in js.h:

   static io_object_t jsJoystick::ioDevices[JS_MAX_OSX_DEVICES] ;

...and in jsMacOSX.cxx:

   io_object_t jsJoystick::ioDevices[JS_MAX_OSX_DEVICES] ;

This should fix the problem - I don't understand how it could ever have
compiled in the first place.
