Yeah, but unfortunately all that means is that the man-hours went into
gcj, not Eclipse.

How hard it is to bring up a random java program under gcj depends on
the program.  Some programs do bad things (use of com.sun.* is a
typical problem, for instance) and are difficult.  Some programs are
well-behaved and don't use the few packages gcj does not support, and
are easy.  Unless you're an expert on both the package and gcj it is
hard to predict the amount of effort without trying it.
