Hm, in the ABI docs its alignment rules are only listed for ppc, not  
ppc64 or IA-32...

Mac68K differs from Packed encoding there, so Pack=1 would not seem to  
be the ultimate solution in all cases. Pack=2 might work better,  
except for vector (16), not sure how char (1) fits into this. In the  
worst case a custom helper for mashalling IntPtr <-> struct via Mac68K  
might need to be implemented?
