I am not sure what is the best way to address this warning.

size_t seems to be architecture dependent. On my computer (intel64)
size_t is long unsigned int, but in this test it is int unsigned.

Are there any suggestions on what is the best way to deal with this?

casting size_t to long unsigned int will work, but it sounds kind of
ugly.


thank you,
