More Tru64 errors

Sat Dec 8 18:38:00 GMT 2001

I found something. I configured gcc without "--enable-threads=posix"
(because gc was within pthreads when it cored) and my test program works.
Now I can not create any threaded objects (see example below).
Does gcj support threaded java objects? If not, what is the issue and maybe
I can look into it.
class Test extends Thread
{

 public void run()
 {
 for( int i=0; i < 10000; i++ )
 System.out.println("Hello World, " + i);
 }
 public static void main (String[] args)
 {
 Test t = new Test();
 t.start();
 }
}
