File _service:tar_scm:build-AC_USE_SYSTEM_EXTENSIONS-in-configure.ac.patch of Package flex
From 24fd0551333e7eded87b64dd36062da3df2f6380 Mon Sep 17 00:00:00 2001 From: Explorer09 <explorer09@gmail.com> Date: Mon, 4 Sep 2017 10:47:33 +0800 Subject: [PATCH] build: AC_USE_SYSTEM_EXTENSIONS in configure.ac. This would, e.g. define _GNU_SOURCE in config.h, enabling the reallocarray() prototype in glibc 2.26+ on Linux systems with that version of glibc.
