[GRASS5] R.cost and r.walk

A couple of questions about r.cost and r.walk.

Does r.walk include r.cost functionality? If not, should they be merged? They seem to overlap a lot. Maybe it just needs a flag (and of course relevant code) to switch from isotropic to anisotropic costs?

Is r.walk compiled by default? It doesn’t seem to show up in the current generic linux binaries or in the Debin binaries. It is in the Mac binaries, however.

Michael,

I cc to Steno Fontanari who can give us more details as core author of
r.walk.

Yes, it is compiled by default. No idea why it shouldn't show up also in
Debian.
