+[zlib] Fix zlib sources for compilation with FreeType
+
+We must ensure that they do not issue compiler errors or 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/gzguts.h (COPY): Rename to...
+(COPY__): ... this since `COPY` and `COPY_` conflict with enum values,
+which have 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.
