hi devs,

testing here winGRASS with a possible configuration of the upcoming OSGeo4W Next Generation:

GRASS Version: 7.8.5
Code revision: exported
Build date: 2021-03-01
Build platform: x86_64-w64-mingw32
GDAL: 3.2.1
PROJ: 8.0.0  <==
GEOS: 3.9.1
SQLite: 3.33.0
Python: 3.9.0
wxPython: 4.1.1
Platform: Windows-10-10.0.19041-SP0 (OSGeo4W)

as PROJ behaviour changed extraordinarily over version 4.xx => 5.xx => 6.xx => 7.xx => 8.0.0

are there any test cases available to check compatibility of GRASS (7.8.x/7.9dev) with PROJ 8.0.0?

kind regards
Helmut
