Right. It appears to be a MinGW related problem, as I've heard from others
who had the same problem.

Also, when testing for _GLIBCPP_USE_WCHAR_T on MinGW, it's conspicuously
absent, and, searching on Google, I found this posting
(http://www.geocrawler.com/mail/msg.php3?msg_id=9057201&list=6013) from
June, 2002:

"wide char streams aren't fully supported yet in new libstdc++.a.  I'm
working on it."

Even if this may be fixed now in the Linux version of GCC, as was said in
this thread, it may be that the MinGW version lags behind. I've asked at the
MinGW site (the mailing list archive didn't work, so I posted in the
bugtracker, instead), and will get back with any reply.
