Is this the same problem I am seeing on IA64:

/proj/opensrc_nobackup/sje/reg/src/trunk/gcc/dbxout.c:107:12: error:
'debug_nesting' defined but not used [-Werror=unused-variable]
/proj/opensrc_nobackup/sje/reg/src/trunk/gcc/dbxout.c:109:14: error:
'symbol_queue' defined but not used [-Werror=unused-variable]
/proj/opensrc_nobackup/sje/reg/src/trunk/gcc/dbxout.c:110:12: error:
'symbol_queue_index' defined but not used [-Werror=unused-variable]
/proj/opensrc_nobackup/sje/reg/src/trunk/gcc/dbxout.c:111:12: error:
'symbol_queue_size' defined but not used [-Werror=unused-variable]
cc1: all warnings being treated as errors

I think it is coming from this change, though I don't see a ChangeLog
entry for it.

No, it's not the same change.  If you like, you could open a different PR and I
could attach a patch I think works.
