[Message part 1 (text/plain, inline)]
struct timeval is a potential return value of struct getsockopt, but,
when HAVE_STRUCT_LINGER is not defined, scm_t_getsockopt_result may
be too small to hold a struct timeval.

To fix this, struct timeval can be added to the scm_t_getsockopt_result
union.

Regards,
Mike Gran
