I'm not sure what you mean by "calling config.guess early".  I don't
suggest touching config.guess and/or the moment it's called.

That's what I understood and I simply suggest replacing

   if test "x$MSYSTEM" = "xMINGW32" -o "x$MSYSTEM" = "xMINGW64"

with

   case "$(uname -a)" in *MINGW* | *MinGW* )

nothing more.  I must say I have no idea whether such a test is
more or less reliable, so I'll stop here.
