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