You and I are co-authors of the earthmovdist package on R-Forge which is just
that: a small package with Rcpp around a single file you once for help with
in wrapping to C++. Feel free to take it as a stanza.

The problem is very similar to what logging classes do. Maybe time to
revisit our old and simple macros and do something better?

Sorry -- that was a combination of my being one checkout behind on the inline
package and what looks like an actual typo
again -- but as I found out the hard

But with that and rev2699 of Rcpp, you should be good and see that your patch
applied cleanly :)

i) assign 3, 4, 5
ii) copy row 0 as 1
iii) copy col 3 to 4
but I am also a little puzzled by the last submatrix.
I'm sure Romain will weigh in in a few hours.
