In egcs-971105, H.J. Lu's frame.c patch is not included, event
though ChangeLog suggests it.

	...
	From H.J. Lu:
	* frame.c (count_fdes, add_fdes): Skip linked once FDE entries.

The code says:
      /* Skip CIEs and linked once FDE entries.  */
      if (this_fde->CIE_delta == 0 || this_fde->pc_range == 0)
	continue;

so it is not skipping entries when pc_begin == 0.
Is it a typo or just vanished somehow?  In either case, the current
code does not work unless pc_begin check is included.
