The first releases of 6.3.0 made a symlink from r.cats to r.category,
but Windows doesn't have symlinks. The later releases should include a
script (and, on Windows, a batch file) for r.cats which simply
executes r.category.

If the script and/or batch file are missing, you can just create them
as follows.

$GISBASE/scripts/r.cats should contain:

#!/bin/sh
g.message -w "This module has been replaced by r.category" 
exec r.category "$@"

$GISBASE/bin/r.cats.bat should contain:

@"%GRASS_SH%" -c '"%GISBASE%/scripts/r.cats" %*'

[there's a lot of punctuation there, so it's probably safer to copy
one of the other .bat files and just change the script name.]

Similar scripts exist for d.paint.labels (replaced by d.labels) and
p.out.vrml (replaced by r.out.vrml).
