if the ABI alignment is 1, the preferred alignment is 4 and someone asks for an
alignment of 2 then you give them an alignment of 1.  Isn't it wrong to ever
use an alignment less than was explicitly asked for by the user?  Are you sure
you don't want to use the maximum of the ABI and the specified alignment?

Ciao, Duncan.
