-Subject: [PATCH] Unconditionally define _GNU_SOURCE
-
-uClibc also uses _GNU_SOURCE to expose glibc compatible API extensions.
-But toolchain built with uClibc don't define __gnu_linux__. This leads
-to implicit declaration warnings at build time. With GCC 14 these
-warnings become errors by default.
-
-For example:
-
-.../sexpect-2.3.14/server.c: In function 'expect_exact':
-.../sexpect-2.3.14/server.c:630:17: error: implicit declaration of function 'strcasestr'; did you mean 'strcasecmp'?
-  [-Wimplicit-function-declaration]
-  630 |         found = strcasestr(g.expbuf, g.conn.pass.pattern);
-      |                 ^~~~~~~~~~
-      |                 strcasecmp
-
-Define _GNU_SOURCE unconditionally to fix the build.
