varargs vs. stdargs

[Maarten Litmaath]

How about this?

In somefile.h:

EXTERN_VARARGS(void, error, (error_p_type error, ...));
--
In somefile.c:
--
/* VARARGS1 */
VARARGS(void, error, (error_p_type error_p, ...))

	error_p_type	error_p;

	va_list ap;

	VA_START(ap, error_p_type, error_p);
	vfprintf(stderr, error_p->message, ap);
	va_end(ap);
	exit(error_p->status);
