UNIX and Linux Applications

I try to compile Samba 3.0.27a under AIX with LDAP and KErberos.
The configure work fine:
CFLAGS:
-I/opt/pware/include -I/opt/pware/lib/ -I/opt/pware/open_ldap_exec/lib/ -I/software/samba/oldap/usr/lib -I/software/samba/oldap/usr/include

./configure --prefix=/opt/pware/samba/3.0.27a --with-acl-support --with-ads --with-winbind --with-ldap --with-krb5

But when i start make I get the following errors:
passdb/pdb_ldap.c: In function 'ldapsam_get_new_rid':
passdb/pdb_ldap.c:4459: error: incompatible types in assignment
passdb/pdb_ldap.c: In function 'pdb_init_ldapsam':
passdb/pdb_ldap.c:5654: error: incompatible types in assignment
The following command failed:
gcc -I. -I/software/samba/samba_327a/source -I/opt/pware/include -I/opt/pware/include -I/opt/pware/lib/ -I/opt/pware/open_ldap_exec/lib/ -I/software/samba/oldap/usr/lib -I/software/samba/oldap/usr/include -R/opt/pware/include -R/opt/pware/lib/ -R/opt/pware/open_ldap_exec/lib/ -R/software/samba/oldap/usr/lib -R/software/samba/oldap/usr/include -D_SAMBA_BUILD_=3 -I/software/samba/samba_327a/source/iniparser/src -Iinclude -I./include -I. -I. -I./lib/replace -I./lib/talloc -I./tdb/include -I./libaddns -I./librpc -DHAVE_CONFIG_H -I/opt/pware/include -I/opt/pware/berkdb/include -I/opt/pware/berkdb/bin -DLDAP_DEPRECATED -I/software/samba/samba_327a/source/lib -D_SAMBA_BUILD_=3 -O2 -c passdb/pdb_ldap.c -o passdb/pdb_ldap.o
make: 1254-004 The error code from the last command is 1.

I have googled for these errors but I have found no solution.
Can anyone help me please?

I don't know what exactly I have done.
But when I tried to compile the Xth time make did it.
