An understanding of what "compatible types" means.

He said that they are 'compatible enough'. That is not terminology
of C Standard, but terminology of his own. And he seems to
understand it.

In my own translation, 'compatible enough' means that when these
structs are accessed then any sane or even semi-sane compiler will
generate code that will have the same effect as in case of access
through structures with literally identical declarations. 

 
so struct { long x; } and struct { int x; } are compatible enough,
in situations that are portable enough.
 

I wish they would be, but according to C Standard they are not, ene
when both represent 32-bt signed integer. That's because of misfeature
called 'strong aliasing rules'.
IMO, C would become better without this misfeature.

Bad attempt of analogy.
