-/* In case Configure was not used (we are using a "canned config"
- * such as Win32, or a cross-compilation setup, for example) try going
- * by the gcc major and minor versions. One useful URL is
- * http://www.ohse.de/uwe/articles/gcc-attributes.html,
- * but contrary to this information warn_unused_result seems
- * not to be in gcc 3.3.5, at least. --jhi
- * Also, when building extensions with an installed perl, this allows
- * the user to upgrade gcc and get the right attributes, rather than
- * relying on the list generated at Configure time. --AD
- * Set these up now otherwise we get confused when some of the <*thread.h>
- * includes below indirectly pull in <perlio.h> (which needs to know if we
- * have HASATTRIBUTE_FORMAT).
