I noticed, that you discarded my example of a useful drop-in replacement
of shared libXaw.so with libXaw3d.so, saying:
az: Besides, most of the functionality that libXaw3d
az: provides over libXaw is provided by Gtk+ themes.
This lead me to conclude, you are aware of some other drop-in replacement
for libXaw.

I resent the personal reference here.

I have no objections whatsoever to changes to shared lib numbers. I
oppose to storing the information _in the binary_ and _relying on it_.
The initial post I responded to, did not suggest such reliance outside
of resolving interports' dependencies, but I'm afraid we may end up
using it in the run-time linker.

Nothing currently does, indeed.

As I mentioned, I'm using libXaw3d instead of libXaw on all of my
machines. I also like NOT having to rebuild my little programs
when I install new TCL libraries. I'm glad I do not have to recompile
tcsh (and lots of other things) when I upgrade FreeBSD.
Reduction in disk and memory usage is indeed _another_ promise
shared libraries deliver... But it is NOT the one I was talking
about.

Yeah, right, will you shave your back then? I asked you privately
to change your tone and attitude, and to apologise. You refused.
This would be my last response to you on this subject (probably on
other subjects too).
