compiling a SWT-gui with gcj on windows

Hy
 Now i've got a little bit further, by replacing mohans build with 
version gcc33-20030722.
 Just let me tell you, exactly what i want to do. I have serveral 
libraries (.jars) and a jar with our code, which runs fine with java. 
Now i wanted to compile the whole stuff with gcj to make it run natively 
on windows (which i think the users would prefer to java).
 I have library-files in my pwd:
boot.jar jface.jar runtime.jar;swt.jar trove.jar xmlParserAPIs.jar 
xercesImpl.jar (they are all in CLASSPATH)
 and
g2gui.jar, which is our piece of work
 i can compile every single file with
 > gcj -fjni -c filename.jar
which results in filname.o
 if i do the last step (in my poor knowledge of gcc/gcj):
 > gcj --main=net.mldonkey.g2gui.view.G2Gui -s -o g2gui.exe trove.o 
boot.o runtime.o xmlParserAPIs.o xercesImpl.o jface.o g2gui.o 
SWTMessages.o -L. -lswt
 i only get this error:
,---------
Error: 0-bit reloc in dll
`---------
 Perhaps some more could help:
 * I have deleted HTMLDOMImplementation.class from xmlParserAPIs.jar, 
as gcj can not currently use libraries that contain duplicate classes, and
and "xercesImpl.jar" and "xmlParserAPIs.jar" both contain 
"HTMLDOMImplementation.class"
 * I have the latest build from mohan, were the binutils reside in 
i686-pc-mingw32/bin, as far as i understood some mails on this list, 
this is supposed to fix some problems, but not mine :-(
 So far for me, i don't know what i am doing wrong, as i only have(as 
already mentioned) very poor knowledge of gcc/gcj, and i couldn't find 
any good howto on the net. I don't know, wether you need additional 
information, as i'm kind of newbie in compiling with gcc/gcj.
