From: "\"Steven J. Hill\"" <sjhill@realitydiluted.com>
Date: Tue, 30 Aug 2005 03:37:12 +0000
Subject: Add in support for downloading and building the latest snapshot of
 GDB. If you want to debug NPTL binaries, you'll need the latest and greatest.
 Patches for 6.3 will be forward ported where applicable later this week.
