Eric Valette (Article 496) thought that AT&T C++ 2.0 might be efficacious.
I don't think so in this case.

I ran C++/cfront version 2.0 release 2c on his example, and as you can
see below, the C output looks fine.

Eric, did you take your question to where ever you got your cfront port?
It looks like you posted gnu.g++.help.  Are you using gnu g++?


//  C++ source code
class example {
private:
  int a ;
public:
  int  getVal()          { return a ; }
  void setVal( int val ) { a = val ; }
};

example glob ;

void f() {
  example loc;
  int     a = 1 ;
  int     b = 2 ;
  int     resu ;

  loc.setVal(1) ;
  resu = loc.getVal() ;

  glob.setVal(1) ;
  resu = glob.getVal() ;
}
