Please could someone help my in packing a data structure. I  am using DJGPP
as a cross compiler to M68000 and am having trouble packing some data
structures:

struct Packet {
	Byte ID;
	Word Length;
	Byte Data[DATALEN];
};

The above structure is usually expanded into:
	Byte ID, spare Byte, Word Length, Data array......

I wanted to lose the spare Byte which is used to word align the Length
variable.  I tried defining a variable with __attribute__ ((packed)) and
although this changed the assembler code it still left the spare byte. 
What am I doing wrong?
