Re: changes to "range"

[Markus Mützel]

See, e.g., this patch in MXE Octave for possible fixes:
https://hg.octave.org/mxe-octave/file/tip/src/of-control-2-octave-9-compat.patch

But note that some of those changes will break compatibility with Octave 
versions before 7. MXE Octave only cares about compatibility with the latest 
released version and newer.
