When trying to compile the MatrixMath examples I got this warning/errors:

Since I didn't write any part of the code I'm wondering if there's a newer version of the library without bug or if there's something I should change.
I even downloaded and added the WProgram.h but even in this case it doesn't work.
Can anyone help me?

Change Wprogram.h to Arduino.h

Oh thanks, I made a longer way changing Wiring inside WProgram. But the problem was also that strangely I had to re-run the Arduino program several times before it could "see" the library even if it was there.
Thanks
