-The xcode project has not been entirely updated to libpng-1.4.0.
 
-It needs to *not* depend on pnggccrd.c or pngvcrd.c
-
-It needs to PNG_NO_PEDANTIC_WARNINGS in the CFLAGS while building
-the library, but not while building an application.
-
-If an updated version is not received, this project will
-be removed when libpng-1.4.0 is released.
+1 September 2010: Philippe Hausler updated the xcode project to work
+with libpng-1.4.x and added iOS targets for simulator and device.
