-   if they are a word or longer.  Powersets and bit strings whic
-   fit in a byte or short are stored that way by the compiler.

-   The order of the bits follows native bit order:
-   If BITS_BIG_ENDIAN, bit 0 is the most significant bit (i.e. 0x80..00);
-   otherwise, bit 0 is the least significant bit (i.e. 0x1).
-
-   MASK_UNUSED_BITS masks out unused bits in powersets and bitstrings.
-   GET_BIT_IN_WORD(W,B) yields 1 (or 0) if the B'th bit if W is set (cleared).
