You could probably split this into separate parts, unless you think it 
would be easier to get it reviewed as a single chunk.

As I recall, and you can probably tell from where you got the patches 
from, there were some reservations with some parts of this patch.

In particular, it might be better to import a new LTDL version, assuming 
that fixes this problem.  If not, it should probably be fixed upstream.

This stuff is slightly incomplete, as it really needs a DEF-generation 
thing, probably with some sort of versioned ordinal thing, or this will 
have awful storage and load-time performance.  I had started on this, 
and I can submit a patch for this if you have not already started 
working on this.

I have no objections to any of this going in though, except for the below.

I think it would be better to figure out why the top-level LDFLAGS does 
not get propagated properly into java as it does for every other 
language, rather than sticking in this hack.
