Doesn't -malign-double effect the alignment of stack variables and
parameters?

It's more than that.  Changing the alignment of doubles in the stack
changes the ABI; you've got to be careful as hell to make sure that
old code still works correctly.

I've got a copy of Marc's assignment, but haven't had the opportunity
to go back and do anything with the double patches.  Damn I'll be
glad when 1.0.2 gets out the door!
