	a25e85ed	2021-08-17T15:20:25		[gzip] Update sources to zlib 1.2.11 This can be tested by building with the Unix development build make setup devel make or by building the freetype-demos programs with meson setup build -Dfreetype2:zlib=internal meson compile -C out and trying to run `ftview` with a `.pcf.gz` font file. * src/gzip/ftgzip.c, src/gzip/rules.mk: Update for new zlib sources. Also remove the temporary fix introduced in commit 6a431038 to work around the fact that the internal sources were too old. * src/gzip/README.freetype: New file describing the origin of the sources and how they were modified. * src/gzip/patches/*: Patch files applied to original sources. * src/gzip/*: Updated zlib sources with the patch file(s) from `src/gzip/patches/` applied, followed by a conversion with zlib's `zlib2ansi` script.
	602be7c8	2016-12-01T11:36:37		[gzip] Improve building with external zlib (#49673). Building FreeType with external zlib 1.2.8 makes msvc 14 stop with the following error. ftgzip.c zlib-1.2.8\zlib.h(86): error C2061: syntax error: identifier 'z_const' zlib-1.2.8\zlib.h(94): error C2054: expected '(' to follow 'z_const' zlib-1.2.8\zlib.h(94): error C2085: 'msg': not in formal parameter list ... zlib-1.2.8\zlib.h(877): fatal error C1003: error count exceeds 100; stopping compilation The error happens because FreeType keeps an own copy of zlib-1.1.4 under `src/gzip'. When building `src/gzip/ftgzip.c' with FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses #include <zlib.h> which correctly finds an external `zlib.h', but `zlib.h' itself has a line #include "zconf.h" which makes Visual Studio 2015 find `src/gzip/zconf.h' while compiling the files in `src/gzip'. * src/gzip/zconf.h: Rename to... * src/gzip/ftzconf.h: ... this. * src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.
