pass the VTIMEZONE component to icalcomponent_compare_vtimezones(), not
2001-09-06 Damon Chaplin <damon@ximian.com> * src/libical/icalcomponent.c (icalcomponent_merge_vtimezone): pass the VTIMEZONE component to icalcomponent_compare_vtimezones(), not the icaltimezone*. Strangely we weren't getting a compiler error. Fixes bug #5275, hopefully. * src/libical/icaltimezone.c (icaltimezone_dump_changes): updated so it still outputs the same format, even though the '1 Jan 0001' component isn't included any more. svn path=/trunk/; revision=12670
