From 20950a7c047ca08f9317d27866c06587ed51a338 Mon Sep 17 00:00:00 2001 Message-ID: <20950a7c047ca08f9317d27866c06587ed51a338.1758727870.git.sam@gentoo.org> From: Samuel Thibault Date: Tue, 26 Mar 2024 22:15:08 +0100 Subject: [PATCH 1/7] Fix detection of setres*id on GNU/Hurd Like Linux, proper _SOURCE macros need to be set to get declarations of various standard functions, notably setres*id. Now that Debian is using -Werror=implicit-function-declaration this is really required. While at it, define other _SOURCE macros like on GNU/Linux, since GNU/Hurd uses the same glibc. --- configure.ac | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/configure.ac b/configure.ac index 5a865f8e1..2eede34c3 100644 --- a/configure.ac +++ b/configure.ac @@ -1348,6 +1348,13 @@ EOD AC_DEFINE([BROKEN_SETVBUF], [1], [LynxOS has broken setvbuf() implementation]) ;; +*-*-gnu*) + dnl GNU Hurd.
