Sigh... maybe it would be best to declare there shall not be a port to a 
non-Unix OS, except for Windows.  There really are few alternatives 
left.  The only ones I can think of that still have life are IBM's, and 
we don't want to go there.  An MVS port for IBM's mainframes?  I can't 
even begin to list the assumptions in Path.cpp that are false on that 
platform, and, unfortunately, it's not from ignorance. If it can't 
emulate the POSIX api, forget it--and I bet there's POSIX emulation for 
MVS nowadays anyway.
