Hi; this gives some a warning on OpenBSD and NetBSD:

/home/qemu/block/qcow2.c: In function 'qcow2_compress':
/home/qemu/block/qcow2.c:3684:18: warning: assignment discards 'const'
qualifier from pointer target type
     strm.next_in = src;
                  ^

thanks

Hm, looks like they use a really old version of the zlib header, which
doesn't care about const correctness. I'll add a cast to work around it.
