Hi, I've included the upstream patch to fix compilation with gcc-6. However, the package overrides the CXXFLAGS so that no debug information is created and the auto-debug package is empty which equals a lintian warning. In src/configure the flags are forced to "-O3" so I was wondering whether this should be completely removed to make it use the usual Debian CXXFLAGS, or whether "-g -O3" should be provided. Best, Gert
