[Debian-astro-maintainers] Bug#833924: wcstools needs a transition

[Ole Streicher]

Source: wcstools
Version: 3.9.4-1
Severity: serious

The version 3.9.4 of wcstools has incomatible changes in the ABI (wcs.h
etc. some sizes of structures changed), which lead to a failure in
packages like saods9 and montage.

As an example, the test of montage-wrapper (which calls montage) fails:

https://ci.debian.net/data/packages/unstable/amd64/m/montage-wrapper/20160806_073113.autopkgtest.log.gz

This needs a new SONAME and a transition of the dependent packages.
