structure padding is fixable, but it would be a signficant change (moving
structure members around).

Version 1.6.24beta03 [July 2, 2016]
Optimized absolute value calculation in filter selection, similar to
code in the PAETH decoder in pngrutil.c. Build with PNG_USE_ABS to
use this.
Added pngcp to the build together with a pngcp.dfa configuration test.
Added high resolution timing to pngcp.
Added "Common linking failures" section to INSTALL.

XVI. Common linking failures
If your application fails to find libpng or zlib entries while linking:
Be sure "-lz" appears after "-lpng" on your linking command.
Be sure you have built libpng, zlib, and your application for the
same platform (e.g., 32-bit or 64-bit).
If you are using the vstudio project, observe the WARNING in
project/vstudio/README.txt.
XVII. Other sources of information about libpng:
Further information can be found in the README and libpng-manual.txt
files, in the individual makefiles, in png.h, and the manual pages
libpng.3 and png.5.
Using the ./configure script -- 16 December 2002.
=================================================
The ./configure script should work compatibly with what scripts/makefile.*
did, however there are some options you might need to add to configure
explicitly, which previously was done semi-automatically (if you didn't edit
scripts/makefile.* yourself, that is)
CFLAGS="-Wall -O -funroll-loops \
-malign-loops=2 -malign-functions=2" ./configure --prefix=/usr/include \
--with-pkgconfigdir=/usr/lib/pkgconfig --includedir=/usr/include
You can alternatively specify --includedir=/usr/include, /usr/local/include,
/usr/include/libpng16, or whatever.
If you find that the configure script is out-of-date or is not supporting
your platform properly, try running autogen.sh to regenerate "configure",
"Makefile.in", and the other configuration files. Then try configure again.
