This thread, many months ago, did not start out indicating how the OpenBSD
versions of these commands had feature X that ours did not, or indicating
that they were faster or smaller in this or that way. For the bc and dc
commands, the thread consisted of seeing if the bc and dc commands from
OpenBSD were good enough for our tree.
"Technical superiority" stems from the superior program being better than
other programs when assessed by technical criteria. As I recall, the
thread indicated the OpenBSD bc and dc were bigger and slower and less
featureful than the GNU ones. Those are technical criteria and the OpenBSD
bc and dc are not better by those criteria.

How is it not?
The OpenBSD dc and bc have not come out as being better in terms of
technical criteria (performance, correctness) from the things I remember=20
seeing in this thread. So choosing them is not choosing the technically-=20
superior program. You describe them as, "fine." Not "superior" nor=20
"excellent," but "fine."
So once again I ask, how is selecting the OpenBSD versions not a political=
Choosing to replace code with other code due to license is a political=20
decision. It is one the NetBSD project has chosen to make and has=20
indicated it will make in the future. It however still is a political=20
For instance, we now use pax, a non-GPL tool, for our tar. That was one=20
place where we made the political decision to go with a new tool front end=
over the tool we had used for the entire life of the project. So saying it=
is a political decision doesn't mean it's a bad thing nor that we souldn't=
I think the quickest way to get a non-GNU bc and dc in NetBSD is not to=20
replace the code. Phil, who also is a long-term NetBSD developer, has=20
indicated he is open to changing the licensing to a dual-use license.=20
However there is some work needed, which he won't be able to do until this=
summer. If you help him do the work, the license will change and NetBSD=20
will have a non-GPL (well dual-use) bc and dc.
