What does "__initZ" refer to? Does this refer to automatic initialization like "this()"?
Almost, it's the static initializer for that struct, which is omitted because you apparently don't compile/link the module containing the struct declaration. Initialize the char array with zeros (= 0) to make the struct fully zero-initialized, preventing the need for that symbol. chars in D are initialized with 0xFF, unlike byte and ubyte.
