10397	compilation error with mfc-iteratior-support: ambiguous symbol	Tobias Loew	Neil Groves	"Hi,

moving parts of range_const_iterator to the namespace range_detail in file boost/range/const_iterator.hpp leads to ambiguity in /range/detail/mfc.hpp line 747:

(MSVC 11 on Windows Server 2008 R2/x64)

The problem can be resolved by changing the name of

boost::range_detail::range_const_iterator

to

boost::range_detail::range_const_iterator_helper

I expect other begin/end adapters to run into the same problem.
