IMHO, since socklen_t is POSIX, callers should provide an equivalent.

I do that successfully in several projects using this snippet (I
sometime use 'int' instead of 'size_t'):

AC_CHECK_TYPE([socklen_t],, [AC_DEFINE([socklen_t], [size_t],
              [Define to `size_t' if `socklen_t' is missing.])], [
#ifdef HAVE_SYS_TYPES_H
#include <sys/types.h>
#endif
#ifdef HAVE_SYS_SOCKET_H
#include <sys/socket.h>
#endif
#ifdef HAVE_NETDB_H
#include <netdb.h>
#endif
])

Hope this helps,
Simon
