Three trivial problems with the ABI page: Presumably the "Structs" section should be changed to "Structs and Unions", since they also conform to the C ABI. AFAIK unions are name-mangled as if they were structs. This should be stated explicitly. Unions are also missing from the description of the extern(D) calling convention on Windows x86.
