Bart didn't say that types are compatible or non-compatible.
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.
