sysklogd: fix compile error (#18133) sysklogd was failing to build because it didn't know the size of the `union wait` type. Running `git bisect` showed 9744c7768d0e6920623a16a4e9d604de2fd52f34, which bumped glibc from 2.23 to 2.24, as the likely suspect. This is corroborated by evidence such as this email: https://lists.debian.org/debian-glibc/2016/08/msg00069.html Linux from scratch recommends changing `union wait` to `int`: http://www.linuxfromscratch.org/lfs/view/development/chapter06/sysklogd.html Therefore, that's what this commit does. 2016-08-30 22:05:07 +00:00			`--- sysklogd-1.5-old/syslogd.c 2016-08-30 22:50:59.812926945 +0100`
