If we follow your recommendation, I think the best approach is to
use strcasecmp after having changed forward slashes into backward
slashes like I did in my first implementation. That way, we let
strcasecmp deal with the folding.
The downside is that we now end up having to allocate some memory
to hold a copy of the two filenames (in order to do the fixup on
slashes above), whereas we don't need that right now. This is something
that will be needed eventually if someone wants to enhance it to
handle multiple slashes, etc. So adding the couple of string copies
now isn't so bad.
