I see some enums and bools in there - in general the storage size of 
those isn't even guaranteed to be consistent between different compiler 
implementations on the same platform, let alone across multiple 
platforms (especially WRT things like GCC's -fshort-enums).

In practice, under the standard ABIs for 32-bit and 64-bit Arm[1], I'd 
expect basic types other than longs and pointers to be pretty much the 
same; it's the imp-def C stuff I'd be a lot less confident about.
