[gdal-dev] Using the OGR library with FileGDB driver

[Carl Godkin]

Thanks, Even.  You give me hope that I wasn't barking up the completely
wrong tree.  I will attempt to debug a little on my own and post what I
find (if anything).

And I can certainly open a Trac ticket if I find something I think is
working incorrectly.  Thanks!
