From 00a4f836eb369723b148e3f250c850a028778832 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 17 Aug 2021 11:56:36 -0700 Subject: [PATCH] Makefile: Enable -Wzero-length-bounds With all known internal zero-length accesses fixed, it is possible to enable -Wzero-length-bounds globally. Since this is included by default in -Warray-bounds, we just need to stop disabling it. Cc: "Gustavo A. R.
