Thanks, is that code something that you and your company would donate
to the public domain?  If so, it could save us some work.

How does the extension choose which of the alternate pre-1970 (or
whatever) histories to use?  For example, suppose America/Toronto
and America/Montreal are the same after 1970, so zic makes them
links.  Which pre-1970 history does it use, Toronto's or Montreal's?
