Yes, but you aren't supposed to enable it yourself.

See

    http://gcc.gnu.org/onlinedocs/libstdc++/17_intro/howto.html#6

for which preprocessor macros you're allowed to change.

You can look in c++config.h in your installation directory to see whether
_GLIBCPP_USE_WCHAR_T is enabled or not.  If it isn't, that means that your
system doesn't provide enough support for wide characters.  (We have to
rely on the system C library for some things.)

That's... odd.

You might try using one of the recent compiler snapshots for 3.1.
Many things have changed since 3.0.
