Flexible arrays - v confused

C++ compilers also enforce prototype predeclarations (so would C99
compilers if they existed). So exactly which dangerous mistake do you
think I am going to miss?

C++ does require prototypes (though not using that term).

C99 requires _declarations_ but not necessarily prototypes. That is
enough for the return type, as here, but not arguments.
