Hi,

I've some problems with g++ 2.1 on a Sparc with SunOS 4.1.1. String.{h,cc}
is from libg++-2.0.

Here is what's going on.
The file :
===============================================
x.cc
===============================================
#include <String.h>

String y("xxxxx");

main(){
    cout << y << "\n";
}
===============================================

It seems that for the variable y a constructor was never
called. It made me a bit puzzled that g++ uses /lib/crt0.o. Is
this the problem? How do I make g++ use a differnt crt0.o (1.40 used a
different one if I remember it correct.) and where can I get one!
There is no Problem with this with gcc 2.1 on dec-mips-ultrix-4.2. 

Any fix or explanation or flame is welcome....

\Magnus
