Replaced AM_CONFIG_HEADER(config.h) with AC_CONFIG_HEADERS([config.h]) in configure.ac Changed default value of PNG_USER_CACHE_MAX from 0 to 32767 in pngconf.h. Avoid a possible memory leak in contrib/gregbook/readpng.c Revised libpng.3 so that "doclifter" can process it. Changed '"%s"m' to '"%s" m' in png_debug macros to improve portability among compilers. Rebuilt the configure scripts with autoconf-2.69 and automake-1.14.1 Removed potentially misleading warning from png_check_IHDR(). Quiet set-but-not-used warnings in pngset.c Quiet an uninitialized memory warning from VC2013 in png_get_png(). Quiet unused variable warnings from clang by porting PNG_UNUSED() from libpng-1.4.6.
