struct drihdr {
  int magic;      /* magic number 0x601a          */
  long tsize;     /* size of text segment         */
  long dsize;     /* size of data segment         */
  long bsize;     /* size of BSS segment          */
  long ssize;     /* size of symbol table         */
  long reserved1; /* must be zero                 */
  long flags;     /* bit flags for fastload, etc. */
  int  absflag;   /* must be zero                 */
 };

When absflag is not zero, it indicates that there is no fixup code.
However, early versions of TOS do not honor this.
