macOS has had posix_memalign since Mac OS X 10.6 (2009) - at least, that's 
what's in Apple's documentation 
<https://opensource.apple.com/source/Libc/Libc-583/gen/posix_memalign.3.auto.html>. 
We needn't worry about older OS releases, as Apple doesn't support them.

Minix is moribund (its last release was 2014) and is no longer a significant 
porting target.

So the only significant issue for aligned_alloc is performance on native 
Windows. And my guess is that we can make it perform well-enough there, for many 
applications (including your application I think).
