I could be wrong here but the way I understood it, there is no concept
of a working directory at the NT level, that is something that is
maintained by the Win32 layer.

My question is, what does GetCurrentDirectoryW() return if the current
directory is greater than the 260 limit?  Does it choke or does it
switch to the \.\c:\foo syntax?
