It's not an initialization, it's a struct with bitfields. FPC currently 
does not support C-compatible bitfield packing. To get a record with 
equal alignment and size you can declare it as "record data: cuint; 
end;", but there is currently no way in FPC to access the bitfields in a 
portable way across platforms.
