+Subject: [PATCH] build-sys: Detect whether struct statx is defined in
+ sys/stat.h
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Starting with glibc 2.27.9000-36.fc29, include file sys/stat.h will have a
+definition for struct statx, in which case include file linux/stat.h should be
+avoided, in order to prevent a duplicate definition.
+
+    In file included from ../src/basic/missing.h:18,
+		     from ../src/basic/util.h:28,
+		     from ../src/basic/hashmap.h:10,
+		     from ../src/shared/bus-util.h:12,
+		     from ../src/libsystemd/sd-bus/bus-creds.c:11:
+    /usr/include/linux/stat.h:99:8: error: redefinition of ‘struct statx’
+     struct statx {
+	    ^~~~~
+    In file included from /usr/include/sys/stat.h:446,
+		     from ../src/basic/util.h:19,
+		     from ../src/basic/hashmap.h:10,
+		     from ../src/shared/bus-util.h:12,
+		     from ../src/libsystemd/sd-bus/bus-creds.c:11:
+    /usr/include/bits/statx.h:36:8: note: originally defined here
+     struct statx
+	    ^~~~~
+
+Extend our meson.build to look for struct statx when only sys/stat.h is
+included and, in that case, do not include linux/stat.h anymore.
+
+Tested that systemd builds correctly when using a glibc version that includes a
+definition for struct statx.

+Subject: [PATCH] meson: unify linux/stat.h check with other checks and use
+ _GNU_SOURCE
+
+Using _GNU_SOURCE is better because that's how we include the headers in the
+actual build, and some headers define different stuff when it is defined.
+sys/stat.h for example defines 'struct statx' conditionally.
