inheritance - Is it possible to call the constructor of a super class, two classes away from the current class in C++ -

i have 3 classes inherit follows:

class_a   class_b : public class_a   class_c : public class_b 

class_a contains constructor:

public: class_a(const char *name, int kind); 

class_b not contain constructor.

in class_c wish invoke constructor of class_a. like:
class_c(const char *name, int kind) : class_a::class_a(name,kind) {}

the problem cannot add intermediate constructor class_b, because class_b generated code regenerates every time make clean. cannot make lasting changes class_b. needless say, above line of constructor in class_c gives error: "type 'class_a' not direct base of 'class_c'".

is there way may invoke constructor of class_a in subclass class_c, without requiring same type of constructor in class_b?

if can't change code generates b, out of luck, afaik. if a class contains such constructor, maybe can away adding simple member function sets 2 variables , call inside c constructor? may not efficient gets, atleast works.
