SWT's OpenGL implementation is at:
http://dev.eclipse.org/viewcvs/index.cgi/platform-swt-home/opengl/opengl.html?rev=1.13
It compiles for me with GCJ, I'm getting the errors when I try to run 
the compiled app.

Oh, right. That was the error.
gcj -v = gcc version 4.0.0 20040924 (experimental)

Here's part of the makefile... I've been tweaking it so its not 
completely current.

I'll give this a shot.
