My question is this: suppose a user says "I need this variable or type
aligned to an N bit boundary". How can you tell, as a function of N,
whether you can do that or not?
I think the answer is the minimum of MAX_OFILE_ALIGNMENT,
STACK_BOUNDARY and BIGGEST_ALIGNMENT, if there are no bugs. If there
are bugs, you can't, not without fixing those bugs.
