-    PNG_ARM_NEON_INTRINSICS.
+    arm/filter_neon_intrinsics.c; enable with -mfpu=neon.
   Revised pngvalid to generate size images with as many filters as it can
     manage, limited by the number of rows.
   Cleaned up ARM NEON compilation handling. The tests are now in pngpriv.h
     and detect the broken GCC compilers.

+    PNG_ARM_NEON_IMPLEMENTATION to the correct value (2 or 1).  This macro
