The default options are findex=1 and field=decimal. However, field 1
is a category, not a decimal. So, you need to use field=cat, i.e.:

	s.to.rast field=cat input=const output=const_rast

Alternatively, if you aren't interested in the category values, you
can use the -s switch, i.e.

	s.to.rast -s input=const output=const_rast
