Working on Kaffe/X-AWT port...

Hi there!
I only want to let you know, that IÂ´m currently working on a port of 
KaffeÂ´s X-awt to gcj.
Of course the first version will still use JNI but IÂ´ll start replacing 
it with CNI when there are working resuts.
In my opinion a direct binding to the X-lib has the folllowing advantages:
* No need for GTK or another library (only X of course)
* Faster primitive drawing functions, especally important when using 
"lightweight" toolkits based on component.
* very portable: A simply x-wrapper (which implements only the needed 
subset of the X-lib) should do the job.
I hope IÂ´ll get the current version work in two weeks, for now, 
everything compiles fine to bytecode using gcj (3.3 prerelease) (with 
removed gnu/awt java/awt packages) but when compiling source or 
class-files to native code, the following problem(s) ocours: 
"java/awt/BarMenu.java:0: internal compiler error: in expand_expr, at 
expr.c:7304".
I hope I can isolate these problems.
One question: This awt implementation uses an helper class stated in 
kaffe/util/Ptr which seems a replacement for the pointer-emulation using 
ints. They use it, because of 64-bit compatibility. But the Ptr class is 
simply a abstract class, so could anybody please explain me, how that works?

PS: Btw: Is lgpl a problem for gcj?
