Thanks Lucus, Jean-Claude and Jürgen.
This will work.


A few related questions.
1. I can't get rid of gdal1.7, as apparently grass needs it. Is defining 
GDAL_DRIVER_PATH like that going to cause problems for grass?
2. I read (trac.osgeo.org/gdal/wiki/config_options) that if GDAL_DRIVER_PATH is 
undefined the default for windows systems is $BINDIR\bin\gdalplugins . I 
presume in this context that would be c:\osgeo4\bin\gdalpugins . If I put these 
files there and don't define GDAL_DRIVER_PATH ECWs don't work. Did I assume 
incorrectly?
3. That's a whole lot more .dll files than I've got. What are the *4d.dll files?
