[boost] lexical_cast.hpp:102: error: `wstring' is not a member of `std' ?

Hello,

I'm not a boost expert, but I'm using LyX, which has boost (version 1.31.0)
included in its source code.

I have FreeBSD (4.10) and use gcc 3.4.2. When I compile LyX, I get
an error from boost:

[...]
../../boost/boost/lexical_cast.hpp:102: error: `wstring' is not a member of `std'
../../boost/boost/lexical_cast.hpp:102: error: `wstring' is not a member of `std'
../../boost/boost/lexical_cast.hpp:103: error: template argument 1 is invalid
../../boost/boost/lexical_cast.hpp:103: error: explicit specialization of non-template `<type error>'
../../boost/boost/lexical_cast.hpp:162: error: declaration of `operator>>' as non-function
../../boost/boost/lexical_cast.hpp:162: error: expected `;' before '(' token
../../boost/boost/lexical_cast.hpp:168: error: expected `;' before "private"

When I reported this to the LyX list, I was told to forward the problem
to the boost list. There may be a problem here with FreeBSD, gcc 3.4.2 and
boost. Any idea what is going on here?

Thanks,
Rob.
