Removed "#ifdef PNG_1_0_X / #endif" surrounding PNG_READ_16_TO_8_SUPPORTED and PNG_READ_GRAY_TO_RGB_SUPPORTED in pngconf.h. These were added in libpng-1.2.41beta08 and libpng-1.0.51, which introduced a binary incompatibility with libpng-1.0.50. Backported two-pass png_decompress_chunk() algorithm from libpng-1.4.1 Removed PNGAPI declaration of png_calloc() and png_write_sig() in 1ibpng-1.2.X, introduced by mistake in libpng-1.2.41. Return allocated "old_buffer" in png_push_save_buffer() before png_error(), to avoid a potential memory leak. Ported rewritten png_decompress_chunk() by John Bowler from libpng-1.4.1. Define _ALL_SOURCE in configure.ac, makefile.aix, and CMakeLists.txt when using AIX compiler. Removed unused gzio.c from contrib/pngminim gather and makefile scripts Send comments/corrections/commendations to png-mng-implement at lists.sf.net (subscription required; visit https://lists.sourceforge.net/lists/listinfo/png-mng-implement to subscribe) or to glennrp at users.sourceforge.net Glenn R-P
