/* highest ARC instance evaluation struct */ the rest of all there is properly declared with extern, and I think this one was missed. adding extern in front of this one makes the link succeed. Will attach patch in a second. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
