Thanks for the link! I might have a look at that if I get to that point of 
having things otherwise mostly working. The libc++ fs tests do have some 
amount of tests for the path handling operations, that I've got locally 
modified to match what MS STL returns, but your tests of that aspect do 
indeed seem more exhaustive.
