-Subject: [PATCH 01/26] add _GNU_SOURCE to pec_listener.c
-
-In previous patch 0007-replace-SIGCLD-with-SIGCHLD.patch made by Khem Raj
-contains two aspects:
-
-	1. replace SIGCLD with SIGCHLD
-	2. add _GNU_SOURCE to pec_listener.c
-
-The replace SIGCLD with SIGCHLD have been integrated upstream, so make a
-another patch to add _GNU_SOURCE to pec_listener.c comply with Khem Raj's
-previous patch.
