Polygons to raster map

[Marlin Mixon]

Hi all,
   I am a Grass newbie and I'm trying to convert vector files to raster.
I tried using v.to.rast and everything works fine, except I want to get
rid of the "lineal" border from between each polygon, that is, I want all
polygons to touch each other, rather than having this artificial single
raster cell wide separation between them.
   I have looked at the grass-u archives, and I've looked to see if
there are any options on the v.to.rast, but haven't found anything that
will look like it will work.

Any assistance will be greatly appreciated.
