Comment:

 I think that raimue's patch should actually be applied as well. The flat-
 file registry prevents us from having ports with names that differ only in
 case when running on a case-insensitive filesystem (even if we considered
 allowing them a good idea). My patch extends that restriction to case-
 sensitive filesystems. I made sure to use the canonical name whenever
 possible, but it's pretty easy to end up using the name as entered by the
 user, so it could easily happen in future code, breaking things again. We
 should therefore make the filemap treat port names case-insensitively as
 well.

 Of course, my reasoning falls down if the filemap code is used for
 anything other than associating file paths with port names. Is it?
