You are talking about Cygwin programs, while I'm talking about the
native w32 build of Emacs.  The effect of LANG and the way to change
the locale is different for each one of these two.

Again, I was not talking about Cygwin, I was talking about the native
w32 build of Emacs.  It doesn't use the Unicode (UTF-16) APIs, so it
can only support the current codepage when it invokes programs through
the Windows APIs.

I already answered that.  I have nothing to add to what I said.
