The following patch fixes some of the bitrot for the Nintendo DS port.
The support is still basic at the moment, but it allows to run the "general"
test under the current head of tree (parent: 5269:11bd1585efb5 tip).
Most of the patch is mine, but I integrated a couple changes that John
Magnotti posted on Feb 1st.
