Thanks very much Alexander. Attached are two patches. The first one is what
I'll submit upstream. It just contains the change to configure.ac to call
the relevant functions which set HAVE_LC_MESSAGES and HAVE_LANGINFO_CODESET.
The second is what I propose gets added to the book - it's the result
of 'autoreconf -f' on the source tree after the first patch has been applied.
Any objections?
Regards,
Matt.
