Sure, sorry for overlooking that point. What troubles me a bit is that I fail to
find any package already doing that kind of stuff to find a bit of information
on dos and don'ts. After all, gcc-snapshot depends on a quite large set of
libraries, all of which should stumble over this issue at some point!? But
apparently the only alternative seem to be version symbols and to build multiple
versions of the library from a single package.
