I'm not entirely sure I agree with you on this point. We don't explicitly include the C library when linking with $(CC), for example, because it is added implicitly by the tool chain. Is there a reason why we wouldn't want to use $(CXX) to link a C++-based extension? If seems like that's the only reason that the optional 'cxx' parameter to PHP_NEW_EXTENSION exists, unless I've misunderstood the autoconf code (which is entirely possible). I do appreciate that your suggestion also solved my problem, of course.
