Please send queries like this to mingw user list, not me personally.
You'll get quicker and better responses
from the group.

The quickest way to get wide char support with GCC 3.2 is to use STLPort
iostream lib.  Changes in location of C++ files means there are some
site config changes you need to make to STLPort to get it woirking with
3.2.  STLPort also has some  w32 locale support for C++ locale classes,
which is lacking in __GLIBCPP__.   There are other features of STLPort
that, IMHO,  make it more efficient on w32 and more portable amongst w32
compilers.

The second way is to grab the libstdc++ sources, run configure and look
through the config.log to see what prevents #define _GLIBCPP_USE_WCHAR_T
1 from happening.  You will see that configure demands quite a lot,
including libiconv, gettext, as well as some Ansi wchar_t functions not
in msvcrt.dll (mbsrtowc and friends).  Meet those demands.

The third way is to modify the libstdc++ code so that at least a subset
of the  wide iostream functions can be supported with the C runtime
that mingw has available
