A few addons, for the sake of completion:o A quick search for the other macros that don't begin with HAVE_ (such as PACKAGE_###, AC_APPLE_UNIVERSAL_BUILD, etc) seem to indicate that they aren't used in any of the API headers
o /include/cdio++ doesn't seem to use any of the cdio_config.h defineso Removing the need for cdio_config.h will also remove the need for cdio_unconfig.h, which is a desirable outcome.
