This is still the case, but I've got slightly more idea about why behaviour
was poor with --multibyte-enable without assuming wchar_t was UCS-4.
We don't include langinfo.h if MULTIBYTE_SUPPORT is defined, which means
CODESET isn't defined, which means we don't use iconv.  (We had a report
about this a while back, I think from Zvi.)

It doesn't seem worth trying too hard to work out if we don't need
langinfo.h.  I'll apply the following patch and following Oliver's
suggestion back off the other one.

I'm still not getting the resulting multibyte strings handled properly in
Solaris.  I don't know why not or whether they should.  I had a vague
feeling this was basically working...
