I had a look at the code.

I don't really remember all the aspects of how this code works, so I can't really give a good evaluation of it right now, but the code change looks reasonable (nice to use `PathParser`'s classification methods rather than comparing with hardcoded strings - as it avoids arch specific ifdefs here). And as it doesn't change any existing tests, and aligns things to MS STL, it probably is ok.
