* PNG_ARM_NEON_OPT is set in CPPFLAGS (to >0) then arm/arm_init.c will fail
* to compile with an appropriate #error if ALIGNED_MEMORY has been turned
* off.
*
* Note that gcc-4.9 defines __ARM_NEON instead of the deprecated
* __ARM_NEON__, so we check both variants.
*
* To disable ARM_NEON optimizations entirely, and skip compiling the
* associated assembler code, pass --enable-arm-neon=no to configure
* or put -DPNG_ARM_NEON_OPT=0 in CPPFLAGS.
