From mboxrd@z Thu Jan 1 00:00:00 1970 From: Vadym Kochan Date: Sat, 9 May 2020 20:05:03 +0300 Subject: [Buildroot] [PATCH] package/ndisc6: fix for codesourcery compilation Message-ID: <20200509170503.346103-1-vadim4j@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net trace-{udp,tcp}.c uses BSD-style headers, it builds ok on some latest libc compilation because they use: __extension__ union but for example on codesourcery toolchain 4.x version it requires that __FAVOR_BSD is defined. So fix it by defining this define only for tcp/udp headers.
