I believe <intrin.h> is part of the Windows SDKs. They are probably
not on-path if they are installed.
According to MSDN, _aligned_malloc and _aligned_free are from
<malloc.h>. See https://msdn.microsoft.com/en-us/library/8z34s9c6.aspx
You might have better luck calling Intel's _mm_malloc and _mm_free for
the aligned allocations. They are more portable across Windows
platforms.
