Sorry, I forgot to paste below macros. Yes, it's assigned, but this
function just returns default("") or global values. But it seems never
assigned.
loadparam.c #line 394

So the function will return "" or it's assigned value.
char *lp_motd_file(void)
{
return(*(char **)(&Globals.motd_file) ? *(char **)(&Globals.motd_file) :
"");
}
