From 6876487abd8041cd2a718ed7dd9ff6d86560b1ee Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Fri, 13 Jan 2017 11:50:09 +0100 Subject: expr: Add const qualifiers to *2str translation arrays MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add const qualifiers to the "to string" translation arrays used by various *2str() functions. This fixes GCC warnings such as the following when compiling with -Wwrite-strings: expr/byteorder.c:176:25: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] In order to catch these in the future, also add -Wwrite-strings to default CFLAGS.
