Subject: [PATCH] configure: Check for struct icmpstat.

NetBSD no longer has statistics structures. Instead, it stores them as
arrays of integer counters. It's backwards compatible with the old
statistics structures, but the struct definitions are missing. This has
likely been broken on NetBSD for quite some time as a result.
