File 0798-erts-inet-driver-Remove-REUSEADDR-windows-ifdef-ing.patch of Package erlang
From 2a6ac6f3f027fcab6d607599e82714e930d9fde2 Mon Sep 17 00:00:00 2001 From: Micael Karlberg <bmk@erlang.org> Date: Tue, 16 Nov 2021 18:32:14 +0100 Subject: [PATCH] [erts|inet-driver] Remove REUSEADDR windows ifdef'ing The REUSEADDR option was disabled for Windows. The reason for this is that this option *had* issues on Windows, specifically Windows XP, which we no longer support. Therefor, we now treat this option the same way on windows as we do on all other platforms.
