Will you also be resubmitting some form of Daniel Jacobowitz's malloc 
patch that we discussed last August to handle MALLOC_ALIGNMENT > 2 * 
SIZE_SZ?  (And if that gets in, has anyone figured out how to make 
powerpc32 take advantage of the change and use the larger malloc alignment 
it ought to use, while keeping ABI compatibility for old emacs binaries?)
