 As reported by Martin Michlmayr in [https://bugs.debian.org/811886 Debian
 Bug #811886]:
 > 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
