As a follow-up to this still-unresolved issue,
some traffic on the MingW list reveals the same
issue using MingW, which I have also (unsuccessfully)
been experimenting with:
http://www.geocrawler.com/mail/msg.php3?msg_id=9057201&list=6013
http://lists.boost.org/MailArchives/boost/msg41422.php
http://sourceforge.net/mailarchive/message.php?msg_id=1991233
Which has been added to their bug tracker database:
https://sourceforge.net/tracker/index.php?func=detail&aid=664369&group_id=2435&atid=102435
Has anyone else had progress with wchar with either
cygwin on mingw?
