Hmm... maybe I'm missing something here.  What do you mean by "not
possible to show debug info like line numbers"?  I have Binutils 2.19
here, and I do see this:

  { /* 0x15d1 */
    /* file dispnew.c line 318 addr 0x15d7 */
    /* file dispnew.c line 322 addr 0x15e7 */
    /* file dispnew.c line 325 addr 0x15ed */
    /* file dispnew.c line 326 addr 0x15f5 */
    /* file dispnew.c line 327 addr 0x15f8 */
  } /* 0x15fa */
  static void _free_glyph_matrix (struct _glyph_matrix /* id 77 */ *_matrix /* 0x8 */)
  { /* 0x15fa */
    int _i /* 0xfffffffc */;
    /* file dispnew.c line 344 addr 0x1600 */
    /* file dispnew.c line 350 addr 0x1606 */
    /* file dispnew.c line 351 addr 0x1615 */
    /* file dispnew.c line 354 addr 0x161a */
    /* file dispnew.c line 355 addr 0x1622 */
    /* file dispnew.c line 356 addr 0x1634 */
    /* file dispnew.c line 355 addr 0x165e */
    /* file dispnew.c line 359 addr 0x1665 */
    /* file dispnew.c line 360 addr 0x1676 */
    /* file dispnew.c line 362 addr 0x1684 */
  } /* 0x1686 */
  static int _margin_glyphs_to_reserve (struct _window /* id 121 */ *_w /* 0x8 */, int _total_glyphs /* 0xc */, int _margin /* 0x10 */)
  { /* 0x1686 */
    int _n /* 0xfffffffc */;
    int _width /* 0xfffffff8 */;
    double _d /* 0xfffffff0 */;
    /* file dispnew.c line 376 addr 0x168c */
    /* file dispnew.c line 378 addr 0x16a6 */
    /* file dispnew.c line 379 addr 0x16b2 */

etc.  This is output from

  objdump -g -l temacs.exe

Isn't this line number information?  What am I missing?
