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