I have to read in this structure into a program.  The problem is, the
compiler returns its size as 16 bytes when it should be 14 bytes.  If I
change all the variables to unsigned short int then it gives 10 bytes (as it
should be).  If I change the 2nd variable to unsigned short int it gives 12
bytes (as it should be).  But, if I change the last variable to unsigned
short int it gives 16 bytes as the total space occupied.  Just what is going
on here?

typedef struct
{
 unsigned short int   bfType;
 unsigned int            bfSize;
 unsigned short int   bfReserved1;
 unsigned short int   bfReserved2;
 unsigned int            bfOffBits;
}BITMAPFILEHEADER;

Thanks,
