VC++7 is not giving trouble with any tests other than lexical_cast_test. On 
it, the message begins:

D:\boost\site-RC_1_30_0\boost\lexical_cast.hpp(142) : error C2065: 
'InputStreamable' : undeclared identifier

The error messages from various date_time library fails for both Intel 
and  VC++ 6.0 are similar. Here is the Intel message:

D:\boost\site-RC_1_30_0\boost/lexical_cast.hpp(137): error: no operator 
"<<" matches these operands operand types are: 
std::basic_stringstream<wchar_t, std::char_traits<wchar_t>, 
std::allocator<wchar_t>> << const std::basic_string<char, 
std::char_traits<char>, std::allocator<char>> return stream << input;

Plus Robin Hu's posting:

Both seem to indicate a wstring/wchar_t problem.
