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