+Subject: [PATCH] gio: fix compilation without F_{S,G}ETPIPE_SZ
+
+Commit a5778ef7c51044147fe470ea1707dd297f44f880 broke compilation on
+architectures without F_SETPIPE_SZ and F_GETPIPE_SZ such as or1k.
+If those variables are undefined, put back previous behavior, buffer
+size set to 1024 * 64
+
+Fixes:
+ - http://autobuild.buildroot.net/results/398490e07343a931b25ca6ab5c90a75d7a073e9f

+Subject: [PATCH] build with older GCCs
+
+GCC versions up through 4.4.7 (which is used in RHEL 6) do not accept any
+argument for the deprecated attribute. GCC 4.5 and later say the "msg"
+argument is optional. We don't need the messages during Buildroot builds
+anyways.
