Hmmm.  Could you try wrapping the dwarf2_debug_hooks structure in a
#ifdef / #endif like shown and let me know if it links?  Sorry I've
not posted a patch, but my local copy is different to CVS.

Thanks,

Neil.

#ifdef DWARF2_DEBUGGING_INFO
/* The debug hooks structure.  */

struct gcc_debug_hooks dwarf2_debug_hooks =
{
  dwarf2out_init,
  dwarf2out_finish
};
#endif
