Note: deleting a shared library is effectivly bumping its major
number. You didn't change the version # on the package which needs to
happen in such cases.

Did you talk to anyone who actually made one of the distribution files?
You talked to a lot of people, yes. But no one who's beein in the source.

Right. And I support the idea of our library # being different from
Zhao's. That way we can bump major numbers if needed.
I was not aware that this change would be implimented by taking the
static library appart to make the dynamic one. If I'd known that, I'd have
said, "STOP." I realize you are not the person who did this. But you are
treating a very real problem in what I think is the wrong manner - we
should just kill the libtool part rather than delete the libraries.
Please test that. It shouldn't take more than an evening to test, and it
will either work or not. If ripping out the libtool part fixes things,
a.out has shared libs. Otherwise we are where we were - no shared libs

I'm still double-checking, but I thought I had it working w/o -lGL on
ELF. Some programs had problems, some didn't.

That's not for this discussion, but I think it would be a good
thing. Other OS's do it. You just have those symbols resolve to something
which sends a sigbus to the program or something like that.
