after little testing, I succeed to compile winGRASS with ZSTD-support ;-)

:-)

steps:

- compiled zstd-1.3.2 in MSYS2 (other possibility would be to use the
precompiled zstd-binaries from the zstd project)

- added manually exe and dll and the header of zstd to the OSGeo4W-tree

- adapted grass_trunk\mswindows\osgeo4w\package.sh

that's all.

all what would be needed is to include zstd into the OSGeo4W tree. will open
a ticket there.
