There's problem with install Openldap-2.1.12

[ZhangPu <zhang@fjh.fujitsu.com>]

hello everyone.

I am installing Openldap2.1.12 to Solaris8.
I installed cyrus-sasl-1.5.27 and db-4.1.25 well, but not installed Openssl.

When I installed Openldap-2.1.12, I did:
%setenv CC /usr/local/bin/gcc
%setenv CFLAGS "-O -g"
%setenv CPPFLAGS "-I/export/home/zhang/LDAP/V2.1.12/openldap-2.1.2/include -Ddef"
%setenv LDFLAGS "-L/usr/local/lib"
#./configure --with-cyrus-sasl --with-threadsad --without-tls
It's OK
#make depend
It's OK
#make
...
mkdir .libs
/usr/local/bin/gcc -O -g -I../../../include -I../../../include -I.. -I./.. -I/ex
port/home/zhang/LDAP/V2.1.12/openldap-2.1.12/include -Ddef -c init.c  -fPIC -DPI

What's this error? How can I solve it?
Give me helps. Thanks a lot.
