From 65db86f0161c393fd5b082c10837b278adadbff2 Mon Sep 17 00:00:00 2001

Subject: [PATCH] configure_func.sh: Add _GNU_SOURCE define and function
signatures
Modern compilers are getting stricter about include paths and function
signature being known duting compilation e.g. clang-15 now errors out if
a function signature is not found
try.c:1:18: error: call to undeclared function 'getspnam'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
This causes the test of function to fail even though the function is
available in libc. Therefore try to add proper include headers which
define these functions and also define _GNU_SOURCE in every test
since some of GNU/Linux funtions e.g. accept4 are guarged by this define
Upstream-Status: Pending
