State-Changed-Why:

    3448.C: In member function `int X::csuperf(int (X::*)(int))':
    3448.C:43: `6' cannot be used as a member pointer, since it is of type `int'

    3448.C:46: syntax error before `:' token
    3448.C:49: ISO C++ forbids declaration of `printf' with no type
    3448.C:49: `int printf' redeclared as different kind of symbol
    /usr/include/stdio.h:254: previous declaration of `int printf(const char*, 
       ...)'
    3448.C:49: cannot convert `const char*' to `int' in initialization

    the error of significance is on line 43. A pointer to member
    is invoked by

    or
    	(obj->*ptr) (args)
