Hi Werner,

Please note that Varnish 3 is no longer supported, consider upgrading
to 4.x instead.

The value you assign to CXX looks odd. Are you copying CC to CXX?

I'd do CXX="$CC"

Regardless, there's no C++ code in Varnish, it's probably not necessary.

If you think it's a false positive, you can always try to disable this
check and see how the compilation goes.
