[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.

+ [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:

+ '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.
