I think mainly because no one optimized GCJ/GCC for speed... It become 
even worse with GCJ 4.3... Other reasons might be your processor, RAM 
and swap...
But you did notice that compiling swt.jar is only done once, right? It 
is cached in swt-[win|lin].jar.[a|o]. This will be reused in every 
compilation as soon as it exists...

Yes, you don't know in advance which classes you need from swt.jar. Also 
what would happen if you took the cached swt.jar for another project?
