Seems the openldap folks should really use -export-dynamic, which
isn't defined for AIX. We could make it -bexpall but as documented in
the previous mail, it doesn't export everything. So, should we create
a new variable, export_dynamic_cmds? If so, and temporary files are
created by it, how do we clean up?
