I have some problems using virtual functions with DJGPP. Even with this
stripped-down sample:

class class_A {
  public:
    virtual void T() {;}
};
class class_B: public class_A {
  public:
    virtual void T() {;}
};
void main () {
  class_A *a1;
  a1 = new class_A;
  delete a1;
}

When compiling (I mean the linkstep):
gcc test.cpp -o test.exe

I get this error:
e:/djgpp/tmp\ccdaaaaa(.text+0x87):test.cpp: undefined reference to `__rtti_user'

What am I doing wrong???
