[GRASS5] Compression (?) of CELL maps (int)

Question: Are CELL maps compressed? If yes, the compression
rate seems to me much lower than for FCELL.

GRASS:/ssi-data/grass/PERMANENT/cell > l
-rw-r--r-- 1 grass fepssi 78518805 Jun  5 15:42 060150.g.s9_SA_135.int

GRASS:/ssi-data/grass/PERMANENT/cell > gzip 060150.g.s9_SA_135.int

GRASS:/ssi-data/grass/PERMANENT/cell > l
-rw-r--r-- 1 grass fepssi 49847399 Jun  5 15:42 060150.g.s9_SA_135.int.gz

-> 63 %

Can we somehow improve the situation?

Markus
