STATUS: For now, system library builders should use the custom makefiles.
4. June 28, 2007: Pnggccrd.c has been reported to be unreliable on
some 64-bit platforms. It appears to build properly, but it does
not always read files correctly, leading to corrupted output or
to a crash of the application.

Y2K compliance in libpng:

Since the PNG Development group is an ad-hoc body, we can't make

This is your unofficial assurance that libpng from version 0.71 and
upward through 1.2.19beta18 are Y2K compliant. It is my belief that earlier
upward through 1.2.19beta19 are Y2K compliant. It is my belief that earlier

*
* June 23, 2007
* June 28, 2007
*
* Since the PNG Development group is an ad-hoc body, we can't make
* an official declaration.
*
* This is your unofficial assurance that libpng from version 0.71 and
* upward through 1.2.19beta18 are Y2K compliant. It is my belief that earlier
* upward through 1.2.19beta19 are Y2K compliant. It is my belief that earlier
* versions were also Y2K compliant.
*
* Libpng only has three year fields. One is a 2-byte unsigned integer
