+Subject: [PATCH] Add compatibility for gcc 15
+
+Fedora 42 is going to use gcc 15 which changes some warnings into errors. Address the issues raised.
+
+The issues addressed include:
+
+* The RETURN macro is defined differently in two places. Rename one.
+* Both atexit and the sigint and sigterm actions call server_exit().
+ The function arguments differ. Introduce a new generic signal handler
+ to call server_exit() for sigint and sigterm signals.
+
+Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2340025
