Great! How is the testing going?

For the RSB until the patch is merged upstream in newlib, it is preferred
to get patches from tickets or mailing list posts. Since there is a ticket
(2972) for adding ndbm, adding your patch to that and letting the RSB fetch
it from there is the right approach.

Also there is a ticket #2833 which lists POSIX .h files missing in newlib.
It should be updated when all is merged.
