Latest won't compile under Solaris 8

[James M Moya]

Here the setup:

# cat ecn
rm config.cache
CC="cc -O -xarch=v9" ./configure \
        --prefix=/opt/openssh \
        --sysconfdir=/var/ssh \
        --with-rsh=/usr/local/etc/rsh \
        --with-ipv4-default \
        --with-ssl-dir=/usr/local/ssl \
        --with-pam \
        --with-ipaddr-display \
        --with-pid-dir=/var/ssh

ALthough I have tried several different configs, all die at the same spot:

cc -O -xarch=v9 -g -I. -I. -I/usr/local/ssl/include  -I/usr/local/include -DETCDIR=\"/var/ssh\"  -D_PATH_SSH_PROGRAM=\"/opt/openssh/bin/ssh\"  -D_PATH_SSH_ASKPASS_DEFAULT=\"/opt/openssh/libexec/ssh-askpass\"  -D_PATH_SFTP_SERVER=\"/opt/openssh/libexec/sftp-server\"  -D_PATH_SSH_PIDDIR=\"/var/ssh\" -DHAVE_CONFIG_H -c session.c

2.9p1 compiled fine with the same config file. The compilers is Forte 6 update 1up to the the latest patcher level.
