Replace these with versions built using an older toolset (so as to avoid ABI compatibilities when linking on Ubuntu 14.04 for packaging purposes)

      *  ZLIB.INC - Interface to the general purpose compression library
      *
      *  ILE RPG400 version by Patrick Monnerat, DATASPHERE.
      *  Version 1.2.8
      *
      *
      *  WARNING:
      *     Procedures inflateInit(), inflateInit2(), deflateInit(),
      *         deflateInit2() and inflateBackInit() need to be called with
      *         two additional arguments:
      *         the package version string and the stream control structure.
      *         size. This is needed because RPG lacks some macro feature.
      *         Call these procedures as:
      *             inflateInit(...: ZLIB_VERSION: %size(z_stream))
