From 0f7a9c9b7bb1f443f8fd0f18cb66933b2f4ec410 Mon Sep 17 00:00:00 2001 From: Jakub Narebski Date: Fri, 7 Dec 2007 02:27:20 +0100 Subject: [PATCH] autoconf: Add test for OLD_ICONV (squelching compiler warning) Update configure.ac (and config.mak.in) to keep up with git development by adding [compile] test whether your library has an old iconv(), where the second (input buffer pointer) parameter is declared with type (const char **) (OLD_ICONV).
