Subject: Why does cfront 2.0 give this error?
Message-ID: <2135@sunquest.UUCP>

Lines: 59

The example below reproduces what I think is a minor bug in cfront 2.0

Does anyone know why the public namespace for the class constructor has
the protected (or private) class constructors thrown in?

###### sun cfront 2.0 output #######
CC    -sun4 -o prot prot.cc
CC  prot.cc:
"prot.cc", line 36: error: two standard conversions possible for Goo::Goo():  struct Goo *Goo::(SomeStruct *) and  struct Goo *Goo::(char *)
"prot.cc", line 36: error:  main() cannot access Goo::Goo(): protected  member

    struct SomeStruct {
	int i;
    };
    
    SomeStruct *ss;

    Goo(char *nname) {

	return Goo(nss);
    }
    void show() {
	cout << "ss->i is " << ss->i << ", name is " << name << "\n";
    }
};

main() {
    Goo a("harold");
    Goo b(0);	      // line 36, I want to call the public Goo constructor!!!
    Goo c = b.duugh();
    a.show();
    b.show();
    c.show();
