Dear all,
the sin_len and sin_len6 field is not available on all platforms.
Therefore
the code setting these fields is #ifdefed. But there are not tests in
the configure scripts to test for these fields and depending on that
defining SIN_LEN or SIN_LEN6 or not.
I think something like
AC_MSG_CHECKING(for sin_len)
AC_TRY_COMPILE([#ifdef HAVE_SYS_TYPES_H
#include <sys/types.h>
#endif
#include <netinet/in.h>],
[struct sockaddr_in x; x.sin_len = 0;],
[AC_DEFINE(HAVE_SIN_LEN, 1 [Define this if your IPv4 has
sin_len in sockaddr_in struct.])
AC_MSG_RESULT(yes)],
[AC_MSG_RESULT(no)])
AC_MSG_CHECKING(for sin6_len)
AC_TRY_COMPILE([#ifdef HAVE_SYS_TYPES_H
#include <sys/types.h>
#endif
#include <netinet/in.h>],
[struct sockaddr_in6 x; x.sin6_len = 0;],
[AC_DEFINE(HAVE_SIN6_LEN, 1, [Define this if your IPv6
has sin6_len in sockaddr_in6 struct.])
AC_MSG_RESULT(yes)],
[AC_MSG_RESULT(no)])
should be added to configure.in and SIN_LEN/SIN_LEN6 should be changed
to HAVE_SIN_LEN/HAVE_SIN6_LEN
to be consistent with other names.
Best regards
Michael
