Your cut-n-paste foo isn't just up to speed, compare the below and  
try and figure out how what you want differs:

ftabstop=
C ObjC C++ ObjC++ Joined RejectNegative UInteger
-ftabstop=<number>      Distance between tab stops for column reporting

ftemplate-depth-
C++ ObjC++ Joined RejectNegative UInteger
-ftemplate-depth-<number>       Specify maximum template  
instantiation depth

Wdeprecated
C++ ObjC++ Var(warn_deprecated) Init(1) Warning
Warn about deprecated compiler features
