the lint chunk of <stdarg.h>:
#elif defined(lint)
/* Provide a fake implementation for lint's benefit */
#define __va_size(type) \
(((sizeof(type) + sizeof(long) - 1) / sizeof(long)) * sizeof(long))
#define va_start(ap, last) \
((ap) = (va_list)&(last) + __va_size(last))
#define va_arg(ap, type) \
(*(type *)((ap) += __va_size(type), (ap) - __va_size(type)))
#define va_end(ap)
Doesn't have an entry for va_copy().
