If I understand what they intend, though, the documentation isn't clear on this
point:

%{!gtoggle:
  %{gdwarf-2:%{!gstabs*:%{!g0: -idsym}}}\                                       
      %{.c|.cc|.C|.cpp|.cp|.c++|.cxx|.CPP|.m|.mm: \                             
      %{gdwarf-2:%{!gstabs*:%{!g0: -dsym}}}}
}

%(gtoggle:
    %{!gdwarf-2:%{!gstabs*:%{!g0: -idsym}}}\                                    
      %{.c|.cc|.C|.cpp|.cp|.c++|.cxx|.CPP|.m|.mm: \                             
      %{!gdwarf-2:%{!gstabs*:%{!g0: -dsym}}}}
}

that said, I'd have the explain in detail exactly what happens with -g0 and
-gstabs.  You'd have to check to {} nesting to make sure I the } at the very
end is right.
