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.
