int always 32 bits on all platforms?

You end up with mutually exclusive goals for different systems: align to 
(depending on the CPU) 8/16/32/64 bits and make it compact. You just can't 
have both in all cases.

Generally I would expect you get one of three cases: 1) you need to ship 
binary struct from one system to another so you need to match a given layout 
from a different system (in this case avoiding misaligned data is a matter 
of luck), 2) you never ship the data out of the process (just skip all the 
align directives and let DMD align stuff correctly as, I think, it does by 
default) or 3) you need packed data (uses align to align on 8 bits)
