+From 2977ff0df909f939517e9857943938ff84201a26 Mon Sep 17 00:00:00 2001

+Subject: [zlib] Fix zlib sources to compile for FreeType
+
+Fix misc zlib sources to ensure that they do not issue compiler
+warnings when they are compiled as part of src/gzip/ftgzip.c.
+
+* src/gzip/adler32.c: Do not define unused functions when Z_FREETYPE
+ is set.
+
+* src/gzip/crc32.c: Undefined DO1 and DO8 macros that are already
+ defined in adler32.c.
+
+* src/gzip/gzguts.h: Rename COPY macro to COPY__ since COPY and
+ COPY_ conflict with enum values with the same name in
+ zlib.h.
+
+* src/gzip/inflate.c, src/gzip/adler32.c: Omit unused function
+ declarations when Z_FREETYPE is defined.
+
+* src/gzip/zlib.h: Include "ftzconf.h" instead of "zconf.h" to
+ avoid conflicts with system-installed headers. Omit unused
+ function declarations when Z_FREETYPE is defined.
+
+* src/gzip/zutil.h: Use ft_memxxx() functions instead of memxxx().
+ Omit unused function declarations when Z_FREETYPE is defined.
+
+* src/gzip/inflate.h, src/gzip/inftrees.h: Add header guard macros
+ to prevent compiler errors.
