From 8666cf65ea6926b6d8c781ae03891435131911cd Mon Sep 17 00:00:00 2001 From: Peter Eisentraut Date: Thu, 5 Oct 2023 08:43:49 +0200 Subject: [PATCH] Modernize const handling with readline The comment /* On some platforms, readline is declared as readline(char *) */ is obsolete. The casting away of const can be removed. The const in the readline() prototype was added in GNU readline 4.2, released in 2001. BSD libedit has also had const in the prototype since at least 2001. (The commit that introduced this comment (187e865174) talked about FreeBSD 4.8, which didn't have readline compatibility in libedit yet, so it must have been talking about GNU readline in the base system. This checks out, but already FreeBSD 5 had an updated GNU readline with const.)
