Hi I've found that openssh-3.2.2p1 can't be compiled on my Linux 2.0.36, because it doesn't define CMSG_DATA and CMSG_FIRSTHDR in <linux/socket.h>. The patch below solved this problem.

...y and using -O does not. On architectures that do not like unaligned accesses this will break. An extraction of mm_send_fd() look something like this: ############################## struct msghdr msg; char tmp[CMSG_SPACE(sizeof(int))]; struct cmsghdr *cmsg; msg.msg_control = (caddr_t)tmp; cmsg = CMSG_FIRSTHDR(&msg); cmsg->cmsg_len = CMSG_LEN(sizeof(int)); ############################## The bus error happens on the last line when a value is written into cmsg_len.

Hi All-- First, thanks to Timo for solving my last issue. I got dovecot up and running on one of my machines, and it does exactly what I want. Now I'm trying to install dovecot on an older box (glibc 2.0.7 Linux kernel 2.0.36), and encountering some problems: -- firstly autoconf/automake does not seem to correctly deal with the madvise function on this system. It detects that we don't
