+From: =?UTF-8?q?Petr=20P=C3=ADsa=C5=99?= <ppisar@redhat.com>

+Subject: [PATCH] No implicit ints and function declarations
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+GCC 13 or 14 is going to remove some old and by C99 standard obsolete
+features, like implicit int types and implicit function declararations,
+from an implicit gnu18 compilator standard. The compiler will report
+an error instead:
+
+conftest.c:62:1: error: type defaults to 'int' in declaration of 'main'
+   62 | main()
+      | ^~~~
+conftest.c:65:3: error: implicit declaration of function 'exit'
+   65 |   exit(0);
+      |   ^~~~
+
+This patch adjusts the code to remain compilable. For some functions,
+it fixes their return type from int to void. Few functions which
+apparantly are internal to a compilatation unit were made static.
+_AuSendClientPrefix() was declared in a public header.
+
+Tested with an instrumented GCC 13.0.1.
