Removed the use of a macro containing the pre-processor 'defined'
operator. It is unclear whether this is valid; a macro that
"generates" 'defined' is not permitted, but the use of the word
"generates" within the C90 standard seems to imply more than simple
substitution of an expression itself containing a well-formed defined

Backed out the SSE optimization and last CMakeLists.txt to allow time for QA.
Version 1.6.28 [January 5, 2017]
No changes.
+Version 1.6.29beta01 [January 12, 2017]
+ Readded "include(GNUInstallDirs)" to CMakeLists.txt (Gianfranco Costamagna).
+ Moved SSE2 optimization code into the main libpng source directory.
+ Configure libpng with "configure --enable-intel-sse" or compile
+ libpng with "-DPNG_INTEL_SSE" in CPPFLAGS to enable it.
+ Simplified conditional compilation in pngvalid.c, for AIX (Michael Felt).
+
+Version 1.6.29beta02 [February 22, 2017]
+ Avoid conditional directives that break statements in pngrutil.c (Romero
+ Malaquias)
+ The contrib/examples/pngtopng.c recovery code was in the wrong "if"
+ branches; the comments were correct.
+ Added code for PowerPC VSX optimisation (Vadim Barkov).
+
+Version 1.6.29beta03 [March 1, 2017]
+ Avoid potential overflow of shift operations in png_do_expand() (Aaron Boxer).
+ Change test ZLIB_VERNUM >= 0x1281 to ZLIB_VERNUM >= 0x1290 in pngrutil.c
+ because Solaris 11 distributes zlib-1.2.8.f that is older than 1.2.8.1,
+ as suggested in zlib FAQ, item 24.
+ Suppress clang warnings about implicit sign changes in png.c
+
+Version 1.6.29 [March 16, 2017]
+ No changes.
+
+Version 1.6.30beta01 [April 1, 2017]
+ Added missing "$(CPPFLAGS)" to the compile line for c.pic.o in
+ makefile.linux and makefile.solaris-x86 (Cosmin).
+ Revised documentation of png_get_error_ptr() in the libpng manual.
+ Silence clang -Wcomma and const drop warnings (Viktor Szakats).
+ Update Sourceforge URLs in documentation (https instead of http).
+
+Version 1.6.30beta02 [April 22, 2017]
+ Document need to check for integer overflow when allocating a pixel
+ buffer for multiple rows in contrib/gregbook, contrib/pngminus,
+ example.c, and in the manual (suggested by Jaeseung Choi). This
+ is similar to the bug reported against pngquant in CVE-2016-5735.
+ Removed reference to the obsolete PNG_SAFE_LIMITS macro in the documentation.
+
+Version 1.6.30beta03 [May 22, 2017]
+ Check for integer overflow in contrib/visupng and contrib/tools/genpng.
+ Do not double evaluate CMAKE_SYSTEM_PROCESSOR in CMakeLists.txt.
+ Test CMAKE_HOST_WIN32 instead of WIN32 in CMakeLists.txt.
+ Fix some URL in documentation.
+
+Version 1.6.30beta04 [June 7, 2017]
+ Avoid writing an empty IDAT when the last IDAT exactly fills the
+ compression buffer (bug report by Brian Baird). This bug was
+ introduced in libpng-1.6.0.
+
+Version 1.6.30rc01 [June 14, 2017]
+ No changes.
+
+Version 1.6.30rc02 [June 25, 2017]
+ Update copyright year in pnglibconf.h, make ltmain.sh executable.
+ Add a reference to the libpng.download site in README.
+
+Version 1.6.30 [June 28, 2017]
+ No changes.
+
+Version 1.6.31beta01 [July 5, 2017]
+ Guard the definition of _POSIX_SOURCE in pngpriv.h (AIX already defines it;
+ bug report by Michael Felt).
+ Revised pngpriv.h to work around failure to compile arm/filter_neon.S
+ ("typedef" directive is unrecognized by the assembler). The problem
+ was introduced in libpng-1.6.30beta01.
+ Added "Requires: zlib" to libpng.pc.in (Pieter Neerincx).
+ Added special case for FreeBSD in arm/filter_neon.S (Maya Rashish).
+
+Version 1.6.31beta02 [July 8, 2017]
+ Added instructions for disabling hardware optimizations in INSTALL.
+ Added "--enable-hardware-optimizations" configuration flag to enable
+ or disable all hardware optimizations with one flag.
+
+Version 1.6.31beta03 [July 9, 2017]
+ Updated CMakeLists.txt to add INTEL_SSE and MIPS_MSA platforms.
+ Changed "int" to "png_size_t" in intel/filter_sse2.c to prevent
+ possible integer overflow (Bug report by John Bowler).
+ Quieted "declaration after statement" warnings in intel/filter_sse2.c.
+ Added scripts/makefile-linux-opt, which has hardware optimizations enabled.
+
+Version 1.6.31beta04 [July 11, 2017]
+ Removed one of the GCC-7.1.0 'strict-overflow' warnings that result when
+ integers appear on both sides of a compare. Worked around the others by
+ forcing the strict-overflow setting in the relevant functions to a level
+ where they are not reported (John Bowler).
+ Changed "FALL THROUGH" comments to "FALLTHROUGH" because GCC doesn't like
+ the space.
+ Worked around some C-style casts from (void*) because g++ 5.4.0 objects
+ to them.
+ Increased the buffer size for 'sprint' to pass the gcc 7.1.0 'sprint
+ overflow' check that is on by default with -Wall -Wextra.
+
+Version 1.6.31beta05 [July 13, 2017]
+ Added eXIf chunk support.
+
+Version 1.6.31beta06 [July 17, 2017]
+ Added a minimal eXIf chunk (with Orientation and FocalLengthIn35mmFilm
+ tags) to pngtest.png.
+
+Version 1.6.31beta07 [July 18, 2017]
+ Revised the eXIf chunk in pngtest.png to fix "Bad IFD1 Directory" warning.
+
+Version 1.6.31rc01 [July 19, 2017]
+ No changes.
+
+Version 1.6.31rc02 [July 25, 2017]
+ Fixed typo in example.c (png_free_image should be png_image_free) (Bug
+ report by John Smith)
+
+Version 1.6.31 [July 27, 2017]
+ No changes.
+
+Version 1.6.32beta01 [July 31, 2017]
+ Avoid possible NULL dereference in png_handle_eXIf when benign_errors
+ are allowed. Avoid leaking the input buffer "eXIf_buf".
+ Eliminated png_ptr->num_exif member from pngstruct.h and added num_exif
+ to arguments for png_get_eXIf() and png_set_eXIf().
+ Added calls to png_handle_eXIf(() in pngread.c and png_write_eXIf() in
+ pngwrite.c, and made various other fixes to png_write_eXIf().
+ Changed name of png_get_eXIF and png_set_eXIf() to png_get_eXIf_1() and
+ png_set_eXIf_1(), respectively, to avoid breaking API compatibility
+ with libpng-1.6.31.
+
+Version 1.6.32beta02 [August 1, 2017]
+ Updated contrib/libtests/pngunknown.c with eXIf chunk.

+ Update libpng.3 and libpng-manual.txt about eXIf functions.
+
+Version 1.6.32beta05 [August 2, 2017]
+ Restored png_get_eXIf() and png_set_eXIf() to maintain API compatability.
+
+Version 1.6.32beta06 [August 2, 2017]
+ Removed png_get_eXIf_1() and png_set_eXIf_1().
+
+Version 1.6.32beta07 [August 3, 2017]
+ Check length of all chunks except IDAT against user limit to fix an
+ OSS-fuzz issue (Fixes CVE-2017-12652).
+
+Version 1.6.32beta08 [August 3, 2017]
+ Check length of IDAT against maximum possible IDAT size, accounting
+ for height, rowbytes, interlacing and zlib/deflate overhead.
+ Restored png_get_eXIf_1() and png_set_eXIf_1(), because strlen(eXIf_buf)
+ does not work (the eXIf chunk data can contain zeroes).
+
+Version 1.6.32beta09 [August 3, 2017]
+ Require cmake-2.8.8 in CMakeLists.txt. Revised symlink creation,
+ no longer using deprecated cmake LOCATION feature (Clifford Yapp).
+ Fixed five-byte error in the calculation of IDAT maximum possible size.
+
+Version 1.6.32beta10 [August 5, 2017]
+ Moved chunk-length check into a png_check_chunk_length() private
+ function (Suggested by Max Stepin).
+ Moved bad pngs from tests to contrib/libtests/crashers
+ Moved testing of bad pngs into a separate tests/pngtest-badpngs script
+ Added the --xfail (expected FAIL) option to pngtest.c. It writes XFAIL
+ in the output but PASS for the libpng test.
+ Require cmake-3.0.2 in CMakeLists.txt (Clifford Yapp).
+ Fix "const" declaration info_ptr argument to png_get_eXIf_1() and the
+ num_exif argument to png_get_eXIf_1() (Github Issue 171).
+
+Version 1.6.32beta11 [August 7, 2017]
+ Added "eXIf" to "chunks_to_ignore[]" in png_set_keep_unknown_chunks().
+ Added huge_IDAT.png and empty_ancillary_chunks.png to testpngs/crashers.
+ Make pngtest --strict, --relax, --xfail options imply -m (multiple).
+ Removed unused chunk_name parameter from png_check_chunk_length().
+ Relocated setting free_me for eXIf data, to stop an OSS-fuzz leak.
+ Initialize profile_header[] in png_handle_iCCP() to fix OSS-fuzz issue.
+ Initialize png_ptr->row_buf[0] to 255 in png_read_row() to fix OSS-fuzz UMR.
+ Attempt to fix a UMR in png_set_text_2() to fix OSS-fuzz issue.
+ Increase minimum zlib stream from 9 to 14 in png_handle_iCCP(), to account
+ for the minimum 'deflate' stream, and relocate the test to a point
+ after the keyword has been read.
+ Check that the eXIf chunk has at least 2 bytes and begins with "II" or "MM".
+
+Version 1.6.32rc01 [August 18, 2017]
+ Added a set of "huge_xxxx_chunk.png" files to contrib/testpngs/crashers,
+ one for each known chunk type, with length = 2GB-1.
+ Check for 0 return from png_get_rowbytes() and added some (size_t) typecasts
+ in contrib/pngminus/*.c to stop some Coverity issues (162705, 162706,
+ and 162707).
+ Renamed chunks in contrib/testpngs/crashers to avoid having files whose
+ names differ only in case; this causes problems with some platforms
+ (github issue #172).
+
+Version 1.6.32rc02 [August 22, 2017]
+ Added contrib/oss-fuzz directory which contains files used by the oss-fuzz
+ project (https://github.com/google/oss-fuzz/tree/master/projects/libpng).
+
+Version 1.6.32 [August 24, 2017]
+ No changes.
+
+Version 1.6.33beta01 [August 28, 2017]
+ Added PNGMINUS_UNUSED macro to contrib/pngminus/p*.c and added missing
+ parenthesis in contrib/pngminus/pnm2png.c (bug report by Christian Hesse).
+ Fixed off-by-one error in png_do_check_palette_indexes() (Bug report
+ by Mick P., Source Forge Issue #269).
+
+Version 1.6.33beta02 [September 3, 2017]
+ Initialize png_handler.row_ptr in contrib/oss-fuzz/libpng_read_fuzzer.cc
+ to fix shortlived oss-fuzz issue 3234.
+ Compute a larger limit on IDAT because some applications write a deflate
+ buffer for each row (Bug report by Andrew Church).
+ Use current date (DATE) instead of release-date (RDATE) in last
+ changed date of contrib/oss-fuzz files.
+ Enabled ARM support in CMakeLists.txt (Bernd Kuhls).
+
+Version 1.6.33beta03 [September 14, 2017]
+ Fixed incorrect typecast of some arguments to png_malloc() and
+ png_calloc() that were png_uint_32 instead of png_alloc_size_t
+ (Bug report by "irwir" in Github libpng issue #175).
+ Use pnglibconf.h.prebuilt when building for ANDROID with cmake (Github
+ issue 162, by rcdailey).
+
+Version 1.6.33rc01 [September 20, 2017]
+ Initialize memory allocated by png_inflate to zero, using memset, to
+ stop an oss-fuzz "use of uninitialized value" detection in png_set_text_2()
+ due to truncated iTXt or zTXt chunk.
+ Initialize memory allocated by png_read_buffer to zero, using memset, to
+ stop an oss-fuzz "use of uninitialized value" detection in
+ png_icc_check_tag_table() due to truncated iCCP chunk.
+ Removed a redundant test (suggested by "irwir" in Github issue #180).
+
+Version 1.6.33rc02 [September 23, 2017]
+ Added an interlaced version of each file in contrib/pngsuite.
+ Relocate new memset() call in pngrutil.c.
+ Removed more redundant tests (suggested by "irwir" in Github issue #180).
+ Add support for loading images with associated alpha in the Simplified
+ API (Samuel Williams).
+
+Version 1.6.33 [September 28, 2017]
+ Revert contrib/oss-fuzz/libpng_read_fuzzer.cc to libpng-1.6.32 state.
+ Initialize png_handler.row_ptr in contrib/oss-fuzz/libpng_read_fuzzer.cc
+ Add end_info structure and png_read_end() to the libpng fuzzer.
+
+Version 1.6.34 [September 29, 2017]
+ Removed contrib/pngsuite/i*.png; some of these were incorrect and caused
+ test failures.
