This is the result of a decision made by the previous maintainer in
2013. From the changelog for unixodbc 2.3.1-1:
- Drop libgtrtst library from libodbc1; this is technically an ABI
change, but nothing has ever used this library so we're not changing
the package name.
- Since the library ABI has not changed in Debian (ever), keep the
package names the same and provide backwards-compatible symlinks to
avoid an unnecessary library transition; and update the symbols/shlibs
to make it clear the old versions of the library don't satisfy these
dependencies any longer.
At that time, the upstream libraries moved to soversion 2, with Debian
packaging that new version plus symlinks named for the old soversion 1
library (but linking to the new version).
This transition, package rename and file redistribution will clean all
of this up.
As noted above, grass, vtk7, mysql-workbench and saga all require
rebuilds once gdal is
rebuilt. tdbcodbc will require a source or NMU upload (see #997057).
