From be89977543c7798411f336236a506bf07b0a3d71 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Wed, 9 May 2012 22:43:30 +0200 Subject: xdiff: remove unused functions The functions xdl_cha_first(), xdl_cha_next() and xdl_atol() are not used by us. While removing them increases the difference to the upstream version of libxdiff, it only adds a bit to the more than 600 differing lines in xutils.c (mmfile_t management was simplified significantly when the library was imported initially). Besides, if upstream modifies these functions in the future, we won't need to think about importing those changes, so in that sense it makes tracking modifications easier.
