There's already an existing GRASS_INT_ZLIB env variable. There should
be only one env variable to enable/disable raster compression.
Just my 0.002 Verizon cents.

Chagrined by a performance hit apparently involving zlib compression, I
patched my local GRASS 7.0 to accept an environment variable that
disables raster compression. At least for the particular DCELL rasters
I've been using, this yields a ~5x improvement in run time during write
operations, at
