No, it does work under Windows. To see it in action:
File Foo.java:
----------------------------------------------------------------
public class Foo {
 public String toString( ) { return "Not in my name!"; }
}
----------------------------------------------------------------
File Bar.java:
----------------------------------------------------------------
public class Bar {
 public static void main(String[] args) {
 System.out.println( Class.forName( "Foo").newInstance( ));
 }
}
----------------------------------------------------------------
Then:
 gcj -C Foo.java
 gcj --main=Bar Bar.java
The fact that it shows Foo.toString( ) means that it works.
To be really certain, change the string in Foo.toString( ) and
just compile (to a .class) Foo.java again without recompiling 
Bar.java - you'll see the updated string.
As Tom pointed out, when you directly reference classes in your
code, they are statically resolved and without libswt.a, you
get the errors you see.
Hope this helps.
