/*
* 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
* _BSD_VA_LIST_ from <machine/ansi.h> and use it.
