From 0be2fe3a750b62cafca9794e37f040624d3a59de Mon Sep 17 00:00:00 2001

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.
