OK. Now that William has helped catch a stupid error on my part, I can report a real problem with compilation on the Mac.
The new improved r.watershed is not compiling. Here is the error.

I am very much looking forward to trying this in GRASS 6.5 and appreciate the effort to backport the multiflow direction improvements. I hope that this issue can be corrected.
