As Nick said, only small pieces of the program are supposd to be compiled
with this option, and they shouldn't be using any library functions or
other parts of the program that use structures with differing layout
in their interface.

If you really want to compile the entire program with a structure size
boundary of 8, you should build all libraries first to match the user code.
