Overview
========

This directory contains an update to the ZLib interface unit,
distributed by Borland as a Delphi supplemental component.

The original ZLib unit is Copyright (c) 1997,99 Borland Corp.,
and is based on zlib version 1.0.4.  There are a series of bugs
and security problems associated with that old zlib version, and
we recommend the users to update their ZLib unit.


Summary of modifications
========================

- Improved makefile, adapted to zlib version 1.2.1.

- Some field types from TZStreamRec are changed from Integer to
  Longint, for consistency with the zlib.h header, and for 64-bit
  readiness.

- The zlib_version constant is updated.

- The new Z_RLE strategy has its corresponding symbolic constant.

- The allocation and deallocation functions and function types
  (TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl,
  and _malloc and _free are added as C RTL stubs.  As a result,
  the original C sources of zlib can be compiled out of the box,
  and linked to the ZLib un
