I don't think this is quite right.  It appears to change the logic  
for aix and linux, which strikes me as wrong.  :-(

If you create darwin_round_type_align... it would be closer.  Ok with  
that change, if you want to do it.

If you have the inclination, would be good to cleanup/contribute all  
of the structure alignment code from the apple branch.  :-)  There  
are plenty of other dark corners that are wrong as well.  :-(
