The transformation of inline function llist_drop to macro llist_drop introduced a bug: the return statement was meant to leave to inline function, but after the transformation it leaves the function that calls the macro.
Also if your compiler is strict enough, it won't compile, as the macro is called from both 'void' and 'non-void' functions.
The fix is changing the code, from if (cond) return; rest; to if (!cond) { rest; }
