From 6997ed9cee88f77e2c58969d55a85fbbfdf2a9d6 Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Wed, 15 Jul 2020 10:32:14 -0700 Subject: [PATCH] Revert mistaken patch for Wine * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_CROSS): Revert patch trying to cater to GNU/Linux builds for Wine. They should use --build as well as --host.
