Version 1.6.7beta04 [October 26, 2013]

Allow clang derived from older GCC versions to use ARM intrinsics. This

causes all clang builds that use -mfpu=neon to use the intrinsics code,

not the assembler code. This has only been tested on iOS 7. It may be

necessary to exclude some earlier clang versions but this seems unlikely.

Changed NEON implementation selection mechanism. This allows assembler

PNG_ARM_NEON_IMPLEMENTATION to the correct value (2 or 1). The

default is "undefined" and the build type is selected in pngpriv.h.
