+Subject: [PATCH] Make configure cope with multiple users/groups with ID 0
+
+If /etc/passwd contains multiple users with UID 0 then user_with_uid0 will
+contain a line feed which results in config.h containing:
+
+ #define UID_0_USER "root
+
+(i.e. without a closing quote.)
+
+The same problem occurs with /etc/group.
+
+Let's only emit the first match in each case so that there is only ever a
+single result.
