From: Baruch Siach Date: Mon, 13 Jul 2015 19:19:38 +0000 (+0300) Subject: atftp: fix build with gcc5 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=aac3f315d9f4ec08728778e08a633f3b193522ed;p=buildroot.git atftp: fix build with gcc5 gcc5 defaults to -std=gnu11 which changes the inline semantics. This leads to multiple definition error with 'extern inline'. See https://gcc.gnu.org/gcc-5/porting_to.html for the details.
