From be05b590e8d5edebd8e35d97af34b0ba7e5350e6 Mon Sep 17 00:00:00 2001 From: Frank Lichtenheld Date: Tue, 28 Nov 2023 11:37:40 +0100 Subject: [PATCH] configure.ac: Remove unused AC_TYPE_SIGNAL macro Recent autoconf warns: configure.ac:448: warning: The macro `AC_TYPE_SIGNAL' is obsolete. And it turns out that we do not actually use RETSIGTYPE. Additionally, there is no reason to do so since as the autoconf documentation says: "These days, it is portable to assume C89, and that signal handlers return void, without needing to use this macro or RETSIGTYPE."
