I hope the above isn't the complete error message.  It should have reported
something about AAIGrid does not support Create() method.  For gdalwarp you
will have to output to a format that supports random writing of raster data
(aka has a Create() method - such as GeoTIFF).  Then translate to Arc/Info
ASCII Grid with gdal_translate.

I would add that 1.1.9 is getting a bit dated.  When you have a chance you might
want to upgrade to 1.2.0.  In any event, this issue doesn't change between
the versions.
