   TYPES:

     natural*	sign determined by host
     signed*    signed type of the given size
     unsigned*  The corresponding insigned type

   SIZES

     *NN	Size based on the number of bits
     *_NN       Size according to the number of bytes
     *_word     Size based on the target architecture's word
     		word size (32/64 bits)
     *_cell     Size based on the target architecture's
     		IEEE 1275 cell size (almost always 32 bits)
     *_address  Fits target address

   NONSPECIFIC

     address_word
		Alias for unsigned_address

     cell_word  Alias for signed_cell

     fp_word    Holds a floating point word.
