GCJ Windows and SWT

I took Erik's suggestion and upgraded:
Reading specs from C:/GCJ/bin/../lib/gcc-lib/mingw32/3.3.1/specs
Reading specs from
C:/GCJ/bin/../lib/gcc-lib/mingw32/3.3.1/../../../libgcj.spec

gcc version 3.3.1 (mingw special 20030804-1)
When I tried rebuilding my app with the new compiler I started getting
'undefined references to ...' against the SWT library
(lib-org-eclipse-swt.a). I assumed I needed to compile SWT with the new
compiler. I tried compiling the SWT sources and I got compile errors like
the following:
C:\GCJ\SWT2.1.1\src>gcj -c org\eclipse\swt\custom\*.java
./org/eclipse/swt/custom/DisplayRenderer.java:66: error: Type `LineCache'
not fo
und in the declaration of the local variable `lineCache'.
 LineCache lineCache = parent.internalGetLineCache();
I fould an earlier email post describing this problem
(http://gcc.gnu.org/ml/java/2003-06/msg00003.html) but no resolution. Has
anyone successfully built SWT on Windows with GCJ 3.3.1? If yes can I have a
copy? Would SWT make a good test source base for GJC? Is there another GUI
toolkit someone would suggest for use with Windows/Unix/Mac OS 10 and GCJ?
