                   Early versions of lupdate complained about

                   when #if, #ifdef or #ifndef was met, and to set
                   yyBraceDepth to that value when meeting #elif or

 /*
   The second part of this source file is the parser. It accomplishes
   a very easy task: It finds all strings inside a tr() or translate()
   call, and possibly finds out the context of the call. It supports
   three cases: (1) the context is specified, as in
   FunnyDialog::tr("Hello") or translate("FunnyDialog", "Hello");
   (2) the call appears within an inlined function; (3) the call
   appears within a function defined outside the class definition.
