openssh for UWIN

[David Korn]

I am enclosing a context diff of the changes that I made to get
openssh working on UWIN.  UWIN is a UNIX operating system layer
that runs on Win32 systems.  For more information on UWIN
go to http://www.research.att.com/sw/tools/uwin/.

I also ran configure using -with-cppflags=-D_BSDCOMP=2.  I don't
know where that information would go with the source code.
Let me know if you need more information.
