I think the point of Noah's query is to find out whether "ancient" is an
accurate description. If indeed nothing newer than Solaris 8 exhibits
the bug, I'd be okay with not working around it, but otherwise we have
some decisions to make.

Also, the post Noah dug up was merely the oldest description of the
problem. I believe what prompted us to actually change the code was
some reports in July 2003:

(the archive threading here is pretty crappy, but you can poke around
among posts of similar date)

Those reports suggest that the problem was observable in many non-C
locales on Solaris 8, not only Icelandic.
