The DWARF support is useful with the minimal sections. In fact, most
of the AIX systems to which I personally have access do not have the
support installed. I don't have control over the patches installed on
most of the systems. This is the difference between a server
operating system and a personal operating system: most people can
install an update on their Mac OS X system, but not everyone can
install an update on their AIX system. Many more people can use and
test the DWARF support on AIX without requiring the latest update.
Thanks, David
