that is: 128K for windowBits=15 + 128K for memLevel = 8 (default values)
plus a few kilobytes for small objects. For example, if you want to reduce
the default memory requirements from 256K to 128K, compile with
make CFLAGS="-O -DMAX_WBITS=14 -DMAX_MEM_LEVEL=7"
Of course this will generally degrade compression (there's no free lunch).
