compiling with GCC 3.0.x (lexical_cast, regex_traits, threads)

Currently I have to change some small things to compile without
warnings on GCC 3.0.x (x=3 really.).

It seems that the checks for sstream of lexical_cast became a little
bit to strong. (GCC 3 has a good sstream.) This:

 #include <boost/config.hpp>

 // The GNU sstream implementation is broken for the purposes of lexical cast.
-# if defined(BOOST_NO_STRINGSTREAM) || (defined(__GNUC__) && !defined(__STL_USE_NEW_IOSTREAMS) || defined(__APPLE_CC__))
+# if defined(BOOST_NO_STRINGSTREAM)
 #  define BOOST_LEXICAL_CAST_USE_STRSTREAM
 # endif

is the change I use. But I have not checked if gcc < 3 handles this
ok, but I would guess so since previous gcc's came with the SGI STL.
Supposedly the "!defined(__STL_USE_NEW_IOSTREAMS)" should make
lexical_cast use sstream, but that does not happen.

Also in regex_traits.hpp I have to do this change:

+      if((f & char_class_unicode) && (c > (uchar_type)255))
          return true;
       return false;
    }

It seems that this code does not handle a wchar_t that is unsigned.

With Boost.Thread I did these changes to avoid some signed/unsigned
warnings:
