+Subject: [PATCH] Fix compilation on gcc >= 14
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+`./configure` fails for gcc >= 14 with the following error
+
+```
+checking "libosip prefix"...
+checking for osip_init in -losip2... yes
+checking for parser_init in -losipparser2... yes
+checking libosip2 version > 3.0.0... *** ERROR: libosip2-3.x.x is required!
+```
+
+which in fact is caused by the test program in `ACX_CHECK_LIBOSIP_VERSION` function in `acinclude.m4` due to
+
+```
+conftest.c:4:3: error: return type defaults to ‘int’ [-Wimplicit-int]
+    4 | main() {
+      | ^~~~
+```
+
+This patch fixes the issue!
