Re: compiling a SWT-gui with gcj on windows

["Simon Rutishauser" <simon dot rutishauser at gmx dot ch>]

Well,

GCJ (especially on windows) is not exactly user-friendly and completely
working. I'd suggest you have a look at the java-devel mailinglist (which
is also accessible through gmane: www.gmane.org gmane.comp.gcc.java.devel)

the people there are really competent and friendly even though lots of
questions are off-topic or so ;-)
