Just to add to the list of win32 problems:

System.loadLibrary() does not work without the hack from here:


Class.forName() does not work because java/lang/natClass.cc ::forName
uses stacktrace.cc ::GetCallingClass which can not work with SJLJ
exceptions.  (this is a regression; Class.forName() worked in previous

Simple test attached for anyone that wants to try.

javac HelloWorld.java
javah -o HelloWorld.h HelloWorld
gcc -Ie:\java\include -Ie:\java\include\win32 -Wl,--add-stdcall-alias -shared 
-o HelloWorld.dll HelloWorld.c
gcj -fjni --main=HelloWorld -o HelloWorld HelloWorld.java

Works with Sun's java and GCJ 4.0, but not 4.2 at this time.
