  37  * Don't use va_list in the err()/warn() prototypes. Va_list is typedef'd in
  38  * <stdarg.h>, so if we include it here we may collide with the utility's
  39  * includes. It's unreasonable for utilities to have to include it to
  40  * include err.h, so we get __va_list from <machine/stdarg.h> and use it.
