[Debian-med-packaging] Bug#811893: swarm-cluster: FTBFS with GCC 6: inconsistent user-defined literal suffixes

[Martin Michlmayr]

Package: swarm-cluster
Version: 2.1.6-1
Severity: important
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-6 gcc-6-literal-suffixes

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
https://gcc.gnu.org/gcc-6/changes.html
