We recently increased the time_t size on certain architectures and some packages started failing to build because they were using a format specifier too narrow for the wider time_t, e.g. #1067829. But the only reason those package FTBFS is they enable either -Werror or some more specific non-default switch like -Werror=format=2, so I suspect much more packages contain similar code but gained only a warning. Isn't this a bad thing? Should we enable at least some combination of -Wformat* switches by default? Should we at least add a new flag to dpkg-buildflags and do some test rebuilds with it enabled? -- WBR, wRAR
