Hi,

I found out recently that Wireshark needs the Z_BLOCK macro which is only in zlib 1.2.0.5 and later. Rather than checking explicitly for the version (which seemed like it would be a pain) I thought I'd check for the macro.

Or do I have to find another solution?
I propose another solution: 
  #ifdef Z_BLOCK
    /* when preset */
  #else
    /* when no */
  #endif
That would obviously be great--but is it reasonably possible? I assumed this was needed for our fancy new zipped-file processing.
