NB: Functions with prototypes containing underscores in type names may be available only with certain extended compilers.
The generator state is keep externally in the state argument, a vector of four UINT_LEAST32_T values, most conveniently initialized with incw_r(). This makes the functions thread safe, and allows creation of a practically-unlimited number of independent families of generators, each with its own state.
