Author: uqs Date: Sat Feb 27 10:18:33 2010 New Revision: 204406 URL: http://svn.freebsd.org/changeset/base/204406 Log: route(8): make WARNS=3 clean - add static and const where appropriate - check pointers against NULL - minor styling nits - it is actually WARNS=6 clean for non-strict alignment platforms This is shamelessly stolen from DragonflyBSD and reduces our diff.
