It does not need to and you don't seem to understand how that is
supposed to work.  If gzip gets invoked as gunzip, then it automatically
infers the "-d" switch.  Which is why usually a symbolic link gunzip ->
gzip is sufficient.  Only that you are running on Windows and Windows
doesn't have symbolic links.  MSys has them, but Windows applications
know nothing about that.

MSys tries to provide a POSIX layer on Windows.  NTemacs tries to
provide it's usual functionality in the absence of such layer.  The two
don't fully mix, in the same way that Cygwin and NTemacs don't.  The
solution is to stay in one world or the other or learn to live with
the roughness around the edges.
