That's gif2png's fault, not libpng's (it's using an obsolete function that has 
been deprecated since libpng 0.9).

gif2png is not a part of libpng, and not shipped with Red Hat Linux, so 
there's nothing we can do about it.

Recommendations:
1) Check wherever you got gif2png - maybe they've released a new version that 
fixes this problem.

2) Use ImageMagick's convert tool instead (syntax: convert filename.gif 
filename.png). It is included in Red Hat Linux, so you don't need a new 
download.
