| Compilation was okay with Octave 2.1.50 and if I replace the lines like:
|
| Octave_map A;
| char** names;
| // ...
| A[*names++] = *GetDataset(Cur);
|
| by:
|
| A.assign (*names++, *GetDataset(Cur));

Because there was no easy way to distinguish when it was used for
extracting values vs. assignment and the semantics required by each
are different.

No.
