Bitfield Support, also 3pragma pack?

Does Dynamic C have no way of using bitfields?

For example:
typedef struct structure
{
int i8uNumber;
int bf4FlagsBank1:4;
int bf2FlagsBank2:2;
int bf2FlagsBank3:2;
};

Also, I find no reference to support for a #pragma pack type of directive for proper structure packing. Does anybody know how this is accomplished on this system?
