[jnc-users] SWT compile

Hi Marco,
I had previously had problems with an AWT compile, which after your help
I was able to get working. The corrupted GIF image issue however meant
that we cannot use the compiled .exe so we decided to add an SWT GUI to
our agent, which honestly looks much better but I'm now seeing errors
when attempting to build this.
A search in our source code shows no trace of AWT or Swing, and the
compile completes with the exclude GUI option. The problem lies in
linking; here are some the errors I'm seeing. Any advice would be very
much appreciated.=20
I'm trying to build Windows .exe on Windows with gcc-119844-win.
