Think of "unsigned" as meaning "always greater than or equal to zero."

On all platforms supported by GCC, assigning the value -1 to an
unsigned int causes it to be converted to the value UINT_MAX.  This is
the largest number that can fit in an unsigned int.  The C standard
requires this number to be at least 65535, which is (obviously)
greater than 6.
