[Patch] Silence test failures on darwin9

[Dominique Dhumieres]

The first patch silences hundreds of harmless warnings from Xcode 3.2.x 
due to r205679 and of the kind

warning: DWARFDebugInfoEntry::AppendDependants() -- check on this item TAG_namelist_item: attr =  AT_namelist_item  form = FORM_ref4

The following three patches fix pr54083 for darwin 8 and 9.

The last patch fixes pr54407 and comes from a year ago at

http://gcc.gnu.org/ml/libstdc++/2012-10/msg00111.html

OK for trunk?
