a) Thanks John - will try your patch next.
b) tried:
# project samba configured on Tue Aug  1 18:58:29 2017 by
# waf 1.5.19 (abi 7, python 2070cf0 on aix5)
# using ./buildtools/bin/waf configure --without-ldap --without-ads 
--prefix=/opt/samba --with-static-modules=ALL
#
But do not see any effect by the '--with-static-modules=ALL' as I still 
see nearly 100 shared libraries that need dlopen() calls.

Is this also something different since 'waf'?
