[Debian-med-packaging] Bug#811810: insighttoolkit: doesn't know about GCC 6

[Martin Michlmayr]

Package: insighttoolkit
Version: 3.20.1+git20120521-6
Severity: important
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-6

This package fails to build with GCC 6.  GCC 6 has not been released
yet, but it's expected that GCC 6 will become the default compiler for
stretch.

Note that only the first error is reported; there might be more.  You
can find a snapshot of GCC 6 in experimental.  To build with GCC 6,
you can set CC=gcc-6 CXX=g++-6 explicitly.

You may be able to find out more about this issue at
