4. June 28, 2007: Pnggccrd.c has been reported to be unreliable on
several 64-bit platforms running gcc-3.4.6. It appears to build
properly, but it does not always read files correctly, leading to
corrupted output or to a crash of the application.
STATUS: Appears to be a bug in the 64-bit version of gcc-3.4.6.
Workarounds are to use -DPNG_NO_MMX_CODE or to upgrade gcc to a
newer version.

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 1.2.19beta27 are Y2K compliant. It is my belief that earlier
upward through 1.2.19beta28 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.

* =========================
*
* July 18, 2007
* July 19, 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 1.2.19beta27 are Y2K compliant. It is my belief that earlier
* upward through 1.2.19beta28 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
