Php 4.0.6 doesn't compile with sybase-ct

Following was the configuration options:
# ./configure --with-apxs=/usr/local/apache/bin/apxs --with-mysql --with-xml --enable-track-vars --with-ldap --enable-ftp --with-mcrypt --with-gdbm --with-sybase=/opt/sybase-11.9.2 --with-sybase-ct=/opt/sybase-11.9.2

It configures properly but doesn't complie.

Following were the errors:
