The following example is simplified from ET++.
It compiles under g++ 1.35.0, and CC 1.2 (at least under vax/ultrix),
but not under g++ 1.36.0- (at least not on sony/news).
	--Per

class Class {
public:
    Class(class Class*);
    friend char *ClassDeclFileName (char *p= "Class.h") { return p; }
    friend char *ClassDeclCompDir (char *p= "" ) { return p; }
    Class(char *dn, char *dcd );
};
typedef char *string;
class StringAssoc {
 public:
  friend char *StringAssocDeclFileName (char *p= "AssocArray.h") { return p; }
  friend char *StringAssocDeclCompDir (char *p= "" ) { return p; }
  StringAssoc& operator[] (string s);
};

static Class StringAssocClassMetaImpl0 (StringAssocDeclFileName (), StringAssocDeclCompDir () );
