So how do you determine this `maximum alignment' in a MI fashion?
This would have to be a MD hack at best.

: on my sparc box, the output curently is
: 	char 1 int 4 void 1
: 	char 1 int 4 void 1
: but would change to
: 	char 1 int 4 void 8
: 	char 1 int 4 void 8

...And for LP64 SPARC, it would need to be "16", as doubles are 16-byte
aligned even though "long long" is only 8 bytes.
