Considering that I've solved this problem more than once, and saw
others do it with at least the same success, I think you see problems
where there are none.

It's already solved, in the w32 parts of the code.  If it will ever be
decided that Posix platforms want to behave case-insensitively on
case-insensitive filesystems (I don't expect such a decision any time
soon), it should be easy to port that code to the other platforms.
