I'm not an expert in Borland bugs, so you probably shouldn't be
asking me.  Borland is the compiler with the worst integral constant
handling I've ever seen, except possibly SunPro.  But I guess it's
reasonable to assert that some mention of MPL is missing.  I would
add, at the top, something like:

     By far the easiest way to avoid portability problems with
     integral constants is to use the MPL's integral constant wrapper
     types and its arithmetic and logical metafunctions <link to
     not-yet-existent docs here>.  If you really feel the need to work
     against the bare metal, here are some tips...
