Bug#863845: libstdc++6: adding more Breaks to smoothen upgrades from jessie to stretch

[Andreas Beckmann <anbe@debian.org>]

Package: libstdc++6
Version: 6.3.0-18
Severity: important

Hi,

during my piuparts upgrade tests I identified a few upgrade paths that
could likely be smoothened by adding a few Breaks to libstdc++6:

  libktoblzcheck1c2a				(replaced by libktoblzcheck1v5)
  libterralib					(replaced by libterralib3)
  libmagickcore-6.q16-2				(replaced by libmagickcore-6.q16-3)
  liblhapdf0					(replaced by liblhapdf0v5)
  libspice-client-glib-2.0-8 (<< 0.33)

In these upgrade paths the problematic packages are not removed
or upgraded, but the jessie versions of these (and some other) packages
are kept installed.

I'm now going to try whether that works as expected ...
