    gcc 3.0 reports
    3448.C: In function `int a(int)':
    3448.C:28: warning: control reaches end of non-void function
    3448.C: In function `int b(int)':
    3448.C:34: warning: control reaches end of non-void function
    3448.C: In function `int superf(int (*)(int))':
    3448.C:39: warning: control reaches end of non-void function
    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:44: warning: control reaches end of non-void function
    3448.C: At global scope:
    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
    	(obj.*ptr) (args)
    or
    	(obj->*ptr) (args)
