Thanks to all that replied. This does work. The size is 9.

typedef struct HeaderTag {
    ULONG          HeaderLength;
    CHAR             PackingType;
    USHORT         NumRows;
    USHORT         PackedSize;
    } __attribute__ ((packed)) HeaderType, *pHeaderType;

If anyone is interested, this is from manpages:
----------------------------------------------------------------------------
----------------------------------------
packed
The packed attribute specifies that a variable or structure field should
have the
smallest possible alignment--one byte for a variable, and one bit for a
field,
unless you specify a larger value with the aligned attribute.

Here is a structure in which the field x is packed, so that it
immediately follows a:

struct foo
{
  char a;
  int x[2] __attribute__ ((packed));
};
