Hi, I'm trying to use lexical_cast<int>(std::wstring), on msvc6 with STLPort, and I get compilation errors. The reason for them is that DISABLE_WIDE_CHARS_SUPPORT is defined in the beginning of lexical_cast.hpp. If I add a line to undef this, in the file, it compiles and works fine, which leads me to belice that this define sould not really be defined. I searched a little more and found that it is defined because BOOST_NO_INTRINSIC_WCHAR_T is defined. My understanding is that this define specifies that the environment does not have wchar_t as a real type, but as a typedef. Why should this interfere with lexical_cast? Any suggestions on how to work around this (apart from changing lexical_cast.hpp source at my site? Thanks Ronnie Lazar
