[boost] Gmane archive problems

FYI, this is a notice that appears at the top of Gmane's homepage (http://gmane.org): ------------- Problems January 29th 2004: By mistake Gmane ran an expiry process last night, which means that most of the articles are gone from the spool. They are now being rescued from backup, but this process will likely take a few days. ------------------- Genny.
