Exactly.

For the record, Alexandre's conservativeness is well-justified.
Debian maintainers should feel free to patch individual Debian
packages, but fixing this problem upstream is a lot harder than it
appears at first glance.
The best solution I can come up with is to *always* change a library's
soname when its dependencies change. I believe it was Joel Klecker
who mentioned something about `libapi' patches for egcs that were
supposed to implement this automatically.
Joel, can you comment on this (or somebody else who knows the details)?
