commit e4ee8feed7a2b460bbb202704072c1927015265f

    Don't build with -Werror
    
    New compiler versions might output new warnings by default
    (see #47 for an example), which makes -Werror problematic
    for distributions.
    
    The more specific -Werror= settings are usually not a problem.
    
    The warnings are still shown, but they will no longer break
    the build.
