        Right; interesting.

        So - it is probable that the GNU linker for Linux at least, tolerates
symlinks very nicely. So, I -suspect- that as long as you create
compatibility symlinks:

        ln -s program/libmerged.so ure/lib/libuno_sal.so.3 

        etc. then I imagine the run-time linker will work out they're all the
same (massive) library and link it just once; while ensuring that other
things linked to the original URE (like extensions) carry on working.
But that needs careful testing obviously.

        Of course, that's a Linux-only hack, but ... it might work nicely - I'd
be interested to know :-) It seems to me that the biggest benefits of
LTO would come from in-lining lots of sal/ stuff - string methods etc.

        Anyhow - glad that libmerged is working nicely again.

        Thanks !

                Michael.
