Hi,
trunk's libpng1.6 and libpng1.5 defines the following macro with a space instead of a "_" before SUPPORTED:
#define PNG_READ_16_TO_8 SUPPORTED /* Name prior to 1.5.4 */
This has been fixed in libpng 1.7. Can you please fix it also in the older branches?
Many thanks!

It was fixed at the same time in libpng16 (git and version 1.6.22beta05). It was also fixed in my private libpng15 branch; I'll go ahead and push that now.
