experimentation. It builds well on all of the boxes I have, but I suspect you have to force it to build against libpng 1.2 in order for it to do what it is supposed to. I'll continue to experiment. If you have few spare minutes give it a try and let me know if you can see any discernible difference in the new/old png files. I haven't yet.
libpng14 is the minimum it will build against. If you attempt to build against libpng12, you will get:
brokenpng.c:(.text+0x128): undefined reference to `png_set_longjmp_fn'
