From 51287fb60263530f61b14df5519e10dabe67d2ad Mon Sep 17 00:00:00 2001
From: Florian Weimer <fweimer@redhat.com>
Date: Thu, 24 Nov 2022 13:07:56 +0100
Subject: [PATCH 2/3] acinclude.m4: Add missing <unistd.h> to
AM_SAFETY_CHECK_MKSTEMP
Otherwise, the check fails on a compiler which does not support
implicit function declarations (a language feature removed in 1999).
Upstream-Status: Submitted [https://github.com/fvwmorg/fvwm/pull/100]
