[boost] problems with program_options

Hello,

In my cvs copy of utf8_codecvt_facet.hpp and utf8_codecvt_facet.cpp files
there is CR+CR+LF used as line separator.

Also, gcc 3.3.1 (mingw) claims:
d:/sources/boost/libs/program_options/src/utf8_codecvt_facet.cpp: In member
   function `virtual std::codecvt_base::result

boost::program_options::detail::utf8_codecvt_facet_wchar_t::do_out(mbstate_t
&,
   const wchar_t*, const wchar_t*, const wchar_t*&, char*, char*, char*&)
const
   ':
d:/sources/boost/libs/program_options/src/utf8_codecvt_facet.cpp:229:
warning: comparison
   is always false due to limited range of data type
d:/sources/boost/libs/program_options/src/utf8_codecvt_facet.cpp: In

   int <unnamed>::get_cont_octet_out_count_impl(wchar_t) [with unsigned int

   4]':

d:/sources/boost/libs/program_options/src/utf8_codecvt_facet.cpp:457:
warning: comparison
   is always true due to limited range of data type

Also gcc 3.3.1 generates erros like:
C:/CPP/MINGW/include/c++/3.3.1/bits/basic_ios.h: In instantiation of
`std::basic_ios<wchar_t, std::char_traits<wchar_t> >':
d:/sources/boost/libs/program_options/src/config_file.cpp:145:
instantiated from `std::basic_istream<wchar_t, std::char_traits<wchar_t> >'
d:/sources/boost/libs/program_options/src/config_file.cpp:145:
instantiated from here
C:/CPP/MINGW/include/c++/3.3.1/bits/basic_ios.h:67: error: no type named `
   pos_type' in `struct std::char_traits<wchar_t>'

I found pos_type is defined for char_traits<wchar_t> specialization if
_GLIBCPP_USE_WCHAR_T is set, but os_defines.h sets _GLIBCPP_USE_WSTRING
only. Is it mingw related problem?

Regards,
Janusz
