[gdal-dev] gdalwarp and 900913

Does the gdalwarp distributed in FWtools 2.0.6 know about
epsg:900913 (Google Maps Global Mercator)?  It doesn't seem
to like this:
  ./gdalwarp mymap.tif -t_srs "+init=epsg:900913"

900913 is not in gcs.csv, but it is in cubewerx_extra.wkt in
that same directory.  Can the definition be merged in to
gcs.csv, or can the parameters in that definition be used as
t_srs arguments?  This doesn't work either:

  ./gdalwarp  mymap.tif -t_srs "+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs" > flailing_around.tif

Or do I need to compile gdalwarp from sources to get this
definition?

Thanks,

Wendell
