Hi Sebastian,

sorry for taking so long to respond to your email.
There are some minor problems with your patchset

1) The last patch breaks the build if zlib isn't installed.
   Please use HAVE_ZLIB or something similar to resolve this.

2) Patch 3 breaks the built although that is fixed by patch 4.
   I think I'll let this slip as you're importing code and then
   fixing it and that seems like a reasonable thing to do in this case.
