Here goes:
./configure --prefix=/usr --sysconfdir=/etc/ssh --with-tcp-wrappers

Compiles just about everything until:
gcc -O2 -m486 -fno-strength-reduce -Wall -DETCDIR=\"/etc/ssh\"
    -DHAVE_CONFIG_H   -c ssh.c -o ssh.o
ssh.c: In function `main':
ssh.c:751: warning: implicit declaration of function `daemon'
gcc -o ssh ssh.o sshconnect.o log-client.o readconf.o clientloop.o libssh.a
    -lpam -ldl -lz -lcrypto  -lssl -lcrypto -lbsd 
gcc -O2 -m486 -fno-strength-reduce -Wall -DETCDIR=\"/etc/ssh\"
    -DHAVE_CONFIG_H   -c sshd.c -o sshd.o
sshd.c:16: poll.h: No such file or directory
make: *** [sshd.o] Error 1
Bad exit status from /var/tmp/rpm-tmp.67018 (%build)

The following is me rambling on and trying quick fixes:

In later versions (glibc), daemon is defined in unistd.h as:
unistd.h:extern int daemon __P ((int __nochdir, int __noclose));
Notes, configure DOES check for daemon:
checking for daemon... yes
If I create this manually, it seems to compile.

And poll.h just includes sys/poll.h which defines struct pollfd, and
the functions:
extern int __poll __P ((struct pollfd *__fds, unsigned long int __nfds,
                        int __timeout));
extern int poll __P ((struct pollfd *__fds, unsigned long int __nfds,
                      int __timeout));
If I copy in a poll.h, I get (obviously):

gcc -g -O2 -Wall -DETCDIR=\"/etc/ssh\" -DSSH_PROGRAM=\"/usr/bin/ssh\" 
    -DSSH_ASKPASS_DEFAULT=\"/usr/libexec/ssh/ssh-askpass\" -DHAVE_CONFIG_H
    -c sshd.c -o sshd.o
