I'm sorry for not answering this earlier.  I was a bit uncertain about how
this works, and I thought perhaps Craig had covered things.

 From an inspection what I see is that there is one driver - AVCBin.  It
now supports both E00 and binary coverages.

I have removed the commented out e00 register call in ogrregisterall.cpp
in cvs just now.

Unfortunately, none of this answers why you aren't able to open the e00
files, since RegisterOGRAVCBin should be sufficient.

Is it possible that you are using a different build of OGR for your
program than was used in FWTools?  FWTools is build from the current
development versions.  For instance E00 support was not in GDAL 1.3.2.
