+Subject: [PATCH 2/2] deps/jemalloc: Do not force building in gnu99 mode
+Content-type: text/plain
+
+The jemalloc configure logic switches to gnu11 mode if available,
+and this explicit flags injection prevents that.  The main difference
+seems to be that in gnu99 mode, <stdatomic.h> is presumed to be
+unavailable and is not used.
+
+Submitted upstream: <https://github.com/redis/redis/pull/11583>
