+Subject: [PATCH] Use labs instead of abs
+
+cluevals is array of longs so we have to use labs() instead of abs()
+since abs() returns int
+
+Fixes
+
+keen.c:1458:17: error: absolute value function 'abs' given an argument
+of type 'long' but has parameter of type 'int' which may cause
+truncation of value
