> Hmmm, I have just read through the bug thread and am confused by all the
discussion about PROJ. g.proj does not use PROJ at all (nor any files from
the PROJ distribution) and strings passed with the proj4= option are
interpreted by GDAL/OGR functions, so I don't see how changes to PROJ can
fix the original problem in this report.
Most of us do use the epsg file that come from proj. And that file, in the
4.7.1 version of proj did not contain datum names, but precise
transformation parameters for one of the available transformations. Thus,
the location wizard suddenly did not ask for a choice between datum
transformations.
This issue was actually fixed by the changes in proj, and, as you say,
have nothing to do with the patches. But AFAIU the issue can still be
considered as solved.
AFAIU (again), your patches fixed another bug, and both were mixed up in
this ticket. But both seem to be solved now.
