istarts_with fails when called for a literal widechar string (VS2005 with /Zc:wchar_t-)

| Milestone: | Component: | range | |
| Version: | Boost 1.37.0 | Severity: | Problem |
| Keywords: | istarts_with, is_char_ptr, /Zc:wchar_t- | Cc: | droba@… |
Description
When compiled with the flag /Zc:wchar_t-, this call returns false:
istarts_with(L"Prefix.FollowedByText", L"Prefix")
The reason, as far as I could determine:
When /Zc:wchar_t- is defined, range_detail::is_char_ptr(L"Prefix") returns false, and as_literal() treats its argument as an array. So boost::end() points past the terminating NULL character, and the comparison fails.

This is not something, that can reasonably be fixed inside string_algo library. literal processing is part of range library, therefore i'm reassigning it there.
