problems with exec("rundll32.exe shell32.dll...")

[Andrew dot Ferguson at arm dot com]

hi,

 I'm having trouble getting the code below to execute once compiled with
gcj (~3.3 I think). Running under straight java works fine, but the
produced .exe says

Error in shell32.dll
Missing entry: "ShellExec_RunDLL"

any help would be really appreciated,
thanks,
asjf

import java.io.*;

public class GCJTest {
      public static void main(String [] arg) throws Exception {
            Runtime.getRuntime().exec("rundll32.exe shell32.dll
ShellExec_RunDLL "+new File(arg[0]).getAbsolutePath());
      }
}
