I would argue against such fix in favor of using typecasts directly (such as
"(png_infopp) NULL") instead of creating needless macros.

libpng changelog from 1.0.x to 1.2.x says:

Typecasted NULL definitions such as
   #define png_voidp_NULL            (png_voidp)NULL
were eliminated.  If you used these in your application, just use
NULL instead.

That is, png_*_NULL macros are only useful for maintaining compatibility with
pre-1.2.x versions of libpng, as these macros were dropped right in 1.2.0
(which came out roughly 9 years ago, in 2001).
