From 4ccd9baa59b24ae700ccf39e01dbf36214e48a5f Mon Sep 17 00:00:00 2001 From: Michal Schmidt Date: Fri, 12 Dec 2014 17:48:13 +0100 Subject: configure.ac: add a generic --enable-debug, replace --enable-hashmap-debug There will be more debugging options later. --enable-debug will enable them all. --enable-debug=hashmap will enable only hashmap debugging. Also rename the C #define to ENABLE_DEBUG_* pattern. NOTE: We add the debugging code to hashmap.{c,h} but do not add the option in configure.ac. We may do so at a later time.
