[boost] [boost/limits.hpp]bug? missing CHAR_BIT

When just:

#include <boost/limits.hpp>

is just preprocessed, the output contains
no definition of CHAR_BIT; yet, it's used
(although within a #if..#endif) within
limits.hpp.  Limits.hpp does contain:

#ifdef BOOST_NO_LIMITS
# include <boost/detail/limits.hpp>
#else
# include <limits>
#endif

which makes me wonder, since CHAR_BIT is used
below this code, whether the authors expected
CHAR_BIT to be defined at this point?  BTW,
CHAR_BIT is defined in system header, limits.h.
The reason it hasn't caused a problem so far
was explained in another post:
