    Set Werror=false by default
    
    This makes sense for dev builds but can potentially break the build
    in environment where any library frogr depends on is building with
    warnings, as that would of course break the build.
    
    This has been recently the case for Hurd and FreeBSD (detected by
    Debian), so let's prevent thi from happening by setting saner defaults.
