A recent post on the Snort Mailing lists about some differences in between the gen-msg.map file that is shipped with the Snort tarball, and the file that it shipped in the Snort Rules tarball led us to actually just remove it from the Rules tarball.
This is because this file will only ever change with the release of a version of Snort, and the file should be used out of the Snort tarball when it is released.
Hope this clears up any confusion that existed!
