Yes.  Do you have an administrative account?  It seems in that version 
of Cygwin such accounts automatically get the -p flag added to tar.

I'm still using an earlier Rtools (Rtools 2.12 is moving, and the 
change to Cygwin 1.7 is recent).  But in theory

tar --no-same-permissions

should undo this.  I think the message may be harmless, though.
