Comment (by dave):

 Replying to [comment:6 Sergey Mitsyn <svm at jinr.ru>]:

 > What I'm thinking about now is the fact that Dinkumware used 32-bit
 integer for 32-bit machine architecture instead of 64-bit, thus ignoring
 the requirement to represent any difference, as Steven stated above. Maybe
 Boost could also switch to using 32-bit ptrdiff_t with the same reason as
 Dinkumware does, at least for MSVC?

 {{{ptrdiff_t}}} is supplied by the standard library (i.e. Dinkumware) and
 not defined by Boost.  We use whatever definition we get from the library.
