There is no +guarantee that libpng will continue to build with such configurations; support +for given configurations can be, and has been, dropped between successive minor +releases.

File names should be about 8 characters +long (excluding the .dfa extension). Submitted .dfa files should have names +between 7 and 16 characters long, shorter names (6 characters or less) are +reserved for standard tests. diff --git a/Build/source/libs/libpng/libpng-1.6.16/contrib/conftest/read.dfa b/Build/source/libs/libpng/libpng-1.6.16/contrib/conftest/read.dfa new file mode 100644 index 00000000000..21e88d01a21 --- /dev/null +++ b/Build/source/libs/libpng/libpng-1.6.16/contrib/conftest/read.dfa @@ -0,0 +1,58 @@ +# read.dfa +# Build time configuration of libpng +# +# Author: John Bowler +# Copyright: (c) John Bowler, 2013 +# Usage rights: +# To the extent possible under law, the author has waived all copyright and +# related or neighboring rights to this work.
