I am rehosting a program from the PC to a SUN SPARC10 station and need to get the
data and structures packed.  For the PC I used a #pragma pack(1) in a global
header file and then set the compiler option to pack structures on 1-byte
boundaries.  Two of two example structures are as follows:

typedef struct ddfdef {
	char 	datatype;
	INT16	entrycount;
	INT16	firstentry;
	INT16	lastentry;
	} DDFDEF;

typedef struct ddfdir {
	INT16	paramcount;
	INT32	recordcount;
	INT16	recordsize;
	INT8	recordtype;
	INT8	filenumber;
	INT8	datasetnum;
	char	datatype;
	INT16	recordingsession;
	INT16	nextentry;
	} DDFDIR;

Structure DDFDEF should pack to a size of 7 while DDFDIR should pack to 16.

Using "__attribute__((packed))"  on each structure is successful for DDFDIR but
complains about being a power of 2 for DDFDEF and maintains a size of 8.
Thus one structure does not get packed.

I really need everything packed and am looking for a global method of doing this
(i.e. a command in the make file or such).  Is there a way of accomplishing
this?

Oh, I have defined BITS_PER_WORD to be 16 and UNITS_PER_WORD as 2.

Thanks in advance for any help!!
