In the sandbox vault, there's range_all.zip which, IFAICT, solves this
problem by having a separate class, range_c_max, for including the
max value in the enumeration.  Also next<> and prev<> have been
specialized as well as integral_rank.  In addition, files in aux_/
preprocessed/gcc had to be modified by supplying an explicit
cast from an integral to the enumeration.

Anyway, the tests provided are for size and for_each (which
actually iterates over the whole enumeration).  Also, mpl::minus
had to be specialized for size to work.

Comments and suggested improvements are welcome.
