Is that the sole content of the file? No #includes?? If so try this
program:
#include <unistd.h>
int
main()
{
return (lseek(0,0L,0) < 0);
}
The problem could be that without including unistd.h the arg types to
the lseek call are wrong (FreeBSD uses a 64Bit offset). Thus the third
argument to lseek was trash, and that is the whence argument :-(.
