Obsolete libpng.

Latest stable libpng

1.5 is not stable in my opinion, and even if it was, surely TeX ought to be compilable against libpng versions that are in the wild.  I think this is a TeX bug.

Comment 2 Jindrich Novy 2011-05-13 10:05:03 UTC
Reported this at TeX Live mailing list and it is now fixed in TeX Live upstream:


In any case leaving this bug open as RFE. Thanks.
