align(size_t.sizeof); ?

Well that doesn't seem to work.

Try this:

version(Win64) {
align(8):
} else {
align(4):
}

This will not work as you expect. Just like
---
version(v1) { class }
else { struct }
S { int i; }
---
will not compile. It's D and there is no C preprocessor:
---
version(Win64) {
  align(8):
  ... aligned 8 ...
} else {
  align(4):
  ... aligned 4 ...
}
... default aligned ...

The code overlaps and it is not much smart.

template Aligned(alias Content)
{
 static if(size_t.sizeof==4)
  align(4) struct Aligned{ mixin Content; }
 else
  align(8) struct Aligned{ mixin Content; }
}

Ain't structs aligned on word boundary by default?

version(Win64) {
    private const const_align = 8;
} else {
    private const const_align = 1;

Please support me!!  Please, please!

private template Aligned() {
    ...long code...
}

version(Win64) {
    align(8): mixin Aligned!();
} else {
    align(1): mixin Aligned!();
}
