From 9f1c162e3374250657e3f90c34df19031bb58c93 Mon Sep 17 00:00:00 2001 From: Michael Adam Date: Fri, 28 Aug 2009 14:06:28 +0200 Subject: s3-ldb: update dlinklist.h to match main copy (lib/util/dlinklist.h) This also removes build warnings of redefined macros since it uses the embracing "#ifndef _DLINKLIST_H ... #endif".
