I don't have the authority to reject, just the authority to flame. :)

I was against it because it's not even obvious that this is a variable
declaration without reading the #define.

Also, using __ prefix is illegal. __ is reserved for the
implementation. For all you know, the C library/compiler might define
__align8 for its own purposes. You should use align8 or something not
in the reserved namespace at the very least.

BTW a portable way to align memory on the stack at 8-byte boundary is
to declare it as type double. :) Not sure this works, but it should..
