+Subject: [PATCH] trace-{tcp,udp}.c: fix build on uClibc
+
+Selection of the BSD variant of struct tcphdr/udphdr on uClibc fails
+because of config.h. This is caused by config.h setting _GNU_SOURCE
+and the compat handling (uClibc doesn't have inet6_rth_*) including
+sys/types.h which in term includes features.h, which figures out
+what bsd/gnu/posix variant to use because of:
+
+ /* If _BSD_SOURCE was defined by the user, favor BSD over POSIX.  */
+ #if defined _BSD_SOURCE && \
+    !(defined _POSIX_SOURCE || defined _POSIX_C_SOURCE || \
+      defined _XOPEN_SOURCE || defined _XOPEN_SOURCE_EXTENDED || \
+      defined _GNU_SOURCE || defined _SVID_SOURCE)
+ # define __FAVOR_BSD    1
+ #endif
+
+The current workaround of undefining _GNU_SOURCE after config.h doesn't
+work as features.h has already been evaluated by then. Instead, simply
+don't include config.h as it isn't needed in these two files.
