I've compiled 2.4.23 on AIX 6.1 with the following settings:
export PATH=/usr/vacpp/bin:/usr/vac/bin:$PATH
export CC=cc
export CXX=xlC
export CONFIG_SHELL=/usr/bin/bash
export CONFIG_ENV_ARGS=/usr/bin/bash
export CFLAGS="-qmaxmem=16384 -DSYSV -D_AIX -D_AIX32 -D_AIX41 -D_AIX43 -D_AIX51 -D_AIX52 -D_AIX53 -D_AIX61 -D_ALL_SOURCE -DFUNCPROTO=15 -O -I/opt/freeware/include  -g -I/opt/pware/Berkeley/latest/include -L/opt/pware/Berkeley/latest/lib"
export CPPFLAGS=$CFLAGS
export CXXFLAGS=$CFLAGS
export LIBS="-lpthread"
export F77=xlf
export FFLAGS="-qmaxmem=16384 -O -I/opt/freeware/include -I/opt/pware/Berkeley/latest/include"
export LD=ld
export LDFLAGS="-L/opt/freeware/lib -Wl,-bmaxdata:0x80000000 -L/opt/pware/Berkeley/latest/lib"
export LD_LIBRARY_PATH=/opt/pware/Berkeley/latest
./configure --prefix=/opt/pware/openldap/2.4.23 --with-openssl --with-shared=yes --enable-ppolicy --enable-unique --enable-ssl --enable-debug
I had to apply a patch which replaxced all occurrences of aix5 with aix 6 in aclocal.m4 , and in build/config.guess as well as contrib/ldapc++/config.guess the 
*:AIX:*:[45]) lines with 
*:AIX:*:[456]). 
Worked a charm. Your paths will probably differ ... and I'm pretty sure bash was a must, but you can get it from 
http://www.perzl.org/aix/index.php?n=Main.Bash
