Details:

I see a couple of compiler warnings, when building the upcomeing image-2.10.0
with the upcomeing Octave 5.0.1.

Here is my setup:
* using Ubuntu 18.04
* using a self-compiled Octave 5.0.1 (hg-id 9644c0b7efd8)
* using the stable branch from the current image repo (hg-id dcac3df7936e),
intended to be image-2.10.0
* doing "make release" for the image package

The compiling all succeeds. But I see some ugly compiler warnings during the
build process:

@Avinoam @Carne: Do you have an idea how to remove those compiler warnings for
Octave 5.0 (and still keep the functionality for Octave 4.2 I hope) ? I don't
want all the users to see those warnings when doing "pkg install -forge image"
from inside Octave 5.0.
