In r8-7777-g25949ee33201f2 I updated some URLs to point to copies of the SGI STL docs in the Wayback Machine, because the original pags were no longer hosted on sgi.com. However, I incorrectly assumed that if one archived page was at https://web.archive.org/web/20171225062613/... then all the other pages would be too. Apparently that's not how the Wayback Machine works, and each page is archived on a different date. That meant that some of our links were redirecting to archived copies of the announcement that the SGI STL docs have gone away. This fixes each URL to refer to a correctly archived copy of the original docs. libstdc++-v3/ChangeLog: * doc/xml/faq.xml: Update URL for archived SGI STL docs. * doc/xml/manual/containers.xml: Likewise. * doc/xml/manual/extensions.xml: Likewise. * doc/xml/manual/using.xml: Likewise. * doc/xml/manual/utilities.xml: Likewise. * doc/html/*: Regenerate.
