41 * Don't use va_list in the err/warn prototypes.   Va_list is typedef'd in two
42 * places (<machine/varargs.h> and <machine/stdarg.h>), so if we include one
43 * of them here we may collide with the utility's includes.  It's unreasonable
44 * for utilities to have to include one of them to include err.h, so we get
45 * __va_list from <sys/_types.h> and use it.
