Are there any cases of multi-dimensional arrays? Because those actually have semantic meaning outside of sizeof(), just in things like adding offsets.
Eg something like
int fn(int a[][10])
ends up being equivalent to something like
int fn(int (*a)[10])
and "a+1" is actually 40 bytes ahead of "a", so it does *not* act like an "int *".
(And I might have screwed that up mightily - C multidimensional arrays and the conversions to pointers are really easy to get confused about. Which is why I hope we don't have them)
