Systemverilog packed structs in Quartus II?

Hmm. So copying the typedef into my module appears to work:

`include "types.svh"

module mod_name(i_port, ...)

typedef struct packed {

bit [127:0] field1;

bit [63:0] field2;

bit [127:0] field3;

bit [63:0] field4;

} name_of_struct;

input name_of_struct i_port;

Does Quartus II really not support `including files with common declarations? That seems like such a basic feature.
