[GRASS5] zlib compression for CELL maps

[Jaro Hofierka]

Hello,

I have a problem with a size of integer (CELL) maps. It is strange that 
the size of compressed integer maps is bigger than the same maps in 
floats. Recently, we tried to import srtm files and floating point maps 
took much less disk space then integers :-(
I tried to use the GRASS_INT_ZLIB variable, but the compression flag in 
a header file is still set to 1 (should be 2?). Problably I missed 
something. I re-compiled GRASS using zlib.
Many thanks for any hints!
