This is not a defect. Unless wchar_t is supported properly as
an intrinsic type, it cannot be differentiated from the
corresponding integer type, leading incorrectly to a numeric
rather than a textual conversion.

The following construction doesn't work in vc++ 7.1 now
without /Zc:wchar_t (Treat wchar_t as a built-in type):
int num = ...;
boost::lexical_cast<std::wstring>(num);
I agree with your argument but this statement should work in
this case IMHO.

The behaviour of a basic_string<wchar_t> will depend in turn
on what wchar_t is. Having conversions for wstring supported
when conversions for wchar_t is not a distinct type would be
inconsistent and would rely on more than can be guaranteed
about the interaction between a non-standard I/O stream
and non-standard basic_string implementation.
