The below patch takes care of the warning, but keep in mind am unsure if this is a correct way
to resolve this issue.
Documentation/accounting/getdelays.c: In function âmainâ:
Documentation/accounting/getdelays.c:436:7: warning: variable âiâ set but not used [-Wunused-but-set-variable]

Keep in mind there is another warning with this file, but need am unsure what might be the best solution:
Documentation/accounting/getdelays.c: In function âget_family_idâ:
Documentation/accounting/getdelays.c:172:14: warning: variable ârcâ set but not used [-Wunused-but-set-variable]

Does -Wunused-but-set-variable require gcc 4.6.0?

not sure.. think its part of the whole "have gcc debug and clean things while it builds" feature with 4.6.0
