[arch-dev-public] [signoff] dcron 4.3

In testing 4.2, we've encountered some minor issues, and I have now put version 4.3 in testing. I'd like to get 2 signoffs per arch for this large update. Here's the changelog since 4.2: v4.3 11-Jan-2010 * Internal refactoring to make buffer overflow checks clearer and portability issues more explicit. * Made file argument to -L mandatory; optional args to getopt needs GNU extensions. * Makefile tweaks. Added CRONTAB_GROUP for `make install`. Renamed TIMESTAMPS -> CRONSTAMPS. Additionally, I took Eric's advice to follow the norm not to put /etc/rc.d/crond in the backups array. Enjoy! - P
