Eh?  copperhead for one is failing for exactly this reason:

Bailout called.  Further testing stopped:  failed to execute command "lz4 -d -m
/home/pgbf/buildroot/HEAD/pgsql.build/src/bin/pg_verifybackup/tmp_check/t_008_untar_primary_data/backup/server-backup/base.tar.lz4":

Looks OK as far as it goes ... but do we need anything on the
MSVC side?

Also, I can't help wondering why we have both GZIP_PROGRAM and GZIP
