+Subject: [PATCH] Lua: Fix void return for non-void functions
+
+Commit #c3f3880d caused the functions
+SWIGINTERN int SWIG_Lua_add_namespace_details(lua_State* L,
+swig_lua_namespace* ns)
+and
+SWIGINTERN int SWIG_Lua_namespace_register(lua_State* L,
+swig_lua_namespace* ns)
+to return void when int returns were expected resulting in the build
+failures for plplot's lua bindings for example. This commit fixes the
+issue.
