os.arch and os.name is incorrect

I'm compiling my SWT app using GCJ, and I discovered that os.arch 
and os.name are different than expected. 

Strangely I haven't noticed too many adverse effects of this. SWT seems
to cope reasonably well(except that it searches for motif libraries and
what not, which I saw using http://www.sysinternals.com filemon.exe).

Perhaps this is already fixed... My GCJ superpowers are limited 
to downloading and running MinGW.

Java code:

   String os = System.getProperty("os.name");
   String arch = System.getProperty("os.arch");
   System.out.println("Native binaries for \"" + os + 
                      "\" \"" + arch + "\" native libraries ..");

Output:

- JDK 1.4.1: "Native binaries for  "Windows 2000" "x86" native libraries .."

- GCJ: "Native binaries for  "Windows 2000" "i586" native libraries .."

- Try compiling with gcj -Os and it's even more wrong(I've filed a bug report,
can't remember what it prints out in that case).
