Note that the current versions are povray-3.6.2 and 
povray-3.7.0.beta.37a, and that current development versions may already 
include various other changes.

Did you verify that this is still backward compatible with earlier 
versions of libpng?

Such a change has already been implemented in change #4827 for the 
POV-Ray 3.6 branch (unfortunately just a few days late for 3.6.2); in 
the POV-Ray 3.7 branch, there is neither such a file, nor such functions 
as far as I can see.

This has also been fixed in change #4827, and also in 3.7.0.beta.31.

I guess the developers will not respond too well to such requests, 
especially when accompanied by exclamation marks. For future code 
submissions, you may want to try submitting (A) a detailed problem 
report (preferably on bugs.povray.org), accompanied by (B) a solution 
/proposal/, rather than a demand.
