Re: libstdc++ in a combined tree

No, it's explicit:

if test "$build" != "$host"; then
  # We are being configured with some form of cross compiler.
  GLIBCXX_IS_NATIVE=false
  case "$host","$target" in
      *-*-darwin*,*-*-darwin*)
	. . .
	;;

      *)
	GCC_NO_EXECUTABLES
	;;
  esac
else
  GLIBCXX_IS_NATIVE=true
fi

(remember that $host here is the toplevel $target)
