Changes since the last public release (1.6.0):
Version 1.6.1 [February 16, 2013]
- Made symbol prefixing work with the ARM neon optimizations. Also allow pngpriv.h
- to be included for preprocessor definitions only, so it can be used in non-C/C++
- files. Back ported from libpng 1.7.

Made sRGB check numbers consistent.
Ported libpng 1.5 options.awk/dfn file handling to 1.6, fixed one bug.
- Removed cc -E workround, corrected png_get_palette_max API Tested on SUN OS cc 5.9,
- which demonstrates the tokenization problem previously avoided by using /lib/cpp.
- Since all .dfn output is now protected in double quotes unless it is to be macro
- substituted the fix should work everywhere.
