Yes, I'd leave it alone until then, given that we've had no other
reports of problems.

That being said,
<http://www.busybox.net/lists/buildroot/2006-December/000708.html>
suggests that uClibc lacks wchar.h, at least in some configurations.
<http://sourceware.org/ml/crossgcc/2000-11/msg00116.html> suggests
that <wchar.h> is missing in a standalone ARM processor environment.
<http://www.arcknowledge.com/gmane.comp.gnu.findutils.bugs/2005-12/msg00048.html>
says <wchar.h> is missing in OpenBSD 3.2 by default.  So I suspect
we'll run into the problem eventually.  (But we can ask for help from
whoever does run into it later....)
