#ifndef _STLP_BITSET_H

#define _STLP_BITSET_H

// A bitset of size N has N % (sizeof(unsigned long) * CHAR_BIT) unused 

// bits.  (They are the high- order bits in the highest word.)  It is

// a class invariant of class bitset<> that those unused bits are

// always zero.

// Most of the actual code isn't contained in bitset<> itself, but in the 

// base class _Base_bitset.  The base class works with whole words, not with

// individual bits.  This allows us to specialize _Base_bitset for the

// important special case where the bitset is only a single word.

// The C++ standard does not define the precise semantics of operator[].

// In this implementation the const version of operator[] is equivalent

// to test(), except that it does no range checking.  The non-const version

// returns a reference to a bit, again without doing any range checking.
