What the heck is this supposed to mean? It sounds like in any
case the C compiler's value is used and the attribute is
completely superfluous/useless.
It means it works like C's _Alignas ( constant-expression ) (C11,
6.7.5).

Cause align doesn't work the way you think it does.
In fact I still don't understand how it works at all.
The language align keyword can only

Works fine on Linux.
Maybe the 32Bit check doesn't work for Windoze?
-m32 on Linux yields Error: SIMD vector types not supported on this

This works fine with unaligned movdqu but throws an access

That doesn't work for me, hence using assembler. I get:
