wstring support?

[Michael Ritzert]

Hi,

I wonder whether the wstring support in libstdc++ v3 current CVS is working.
It seems I just can't get configure to define _GLIBCPP_USE_WCHAR_T. Here is how I come to this conclusion:
I'm always compiling the whole gcc CVS and using gcc/configure --enable-threads --prefix=/usr --enable-languages=c+.
After the compile finishes, I do a
find . -type f | grep _GLIBCPP_USE_WCHAR_T | grep define | grep -v defined
in both the source and object directories. All I get is the configure script itself.
Is there anything special I have to do in order to get wstring support? Any other library needed?

I'm running Linux 2.2.14 (SuSE 6.4) and 2.2.16 (SuSE 7.0).
