I found out recently that Wireshark needs the Z_BLOCK macro which is only in zlib 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 */
    /* when no */
That would obviously be great--but is it reasonably possible?  I assumed 
this was needed for our fancy new zipped-file processing.
