Ah, now I can see some sense in these dies.  Looking in the actual
executable I can see this...

So, it appears to list the members of Waypoint.  Is this enough info for
gdb to not say incomplete type?  How can I figure out why gdb is missing
this?  When I explicitly try to reference these members of a Waypoint
object gdb says "There is no member named wpll_".

The containing type for 'Waypoint' points to a die that appears to
describe Waypoint's base class.  I couldn't find any dies relating to
the namespace 'Soi'.

Thanks for the help so far.
Cheers,
Craig.
