It should; what error are you getting or what is going wrong?

As far as I can see those files aren't used for anything and I don't know
why they're there. Where are you hardcoding them?

You should just be able to add it to the ellipse.table, or directly in the
PROJ_INFO file. If the most recent version doesn't work then probably in
my changes I have overlooked something and if you can give some more
details on how I can reproduce the problem I will see about fixing it as
soon as possible.
