Errors when compiling libswt.a under winxp

Subject: Errors when compiling libswt.a under winxp

I am trying to compile the library libswt.a like explain by http://gcc.gnu.org/ml/java/2002-12/msg00105.html the compilation process have positive result generating one library libswt.a of 7.85MB, but the compilation process also generates some warnings and errors. With the obtained library I have compiled the "described Advanced widgets tutorial" like in http://www.cs.umanitoba.ca/~eclipse/, nearly all the demo work except some, e.g. ImageDemo. I have noticed that the instruction

Image img = new Image(display, "EclipseBannerPic.jpg");

causes a crash of the application.

Someone can help me?

Thanks.
