+Subject: [PATCH] 3rdparty/iaxclient: fix declaration of openal_initialize()
+
+In audio_openal.h, openal_initialize() was declared without any
+parameter specified, however the definition takes two. This was valid in
+pre-ANSI C (K&R function declarations) but was removed in C23 and is
+apparently already causing problems:
+
+  https://sourceforge.net/p/flightgear/mailman/message/59181327/
+
+Also move #include "audio_openal.h" from iaxclient_lib.h to where it is
+actually needed (iaxclient_lib.c).
