Or:
- Have both projects in the same repository
- create a third project for the shared files
- Create placeholder-files in the 2 other projects
- After checkout, 'svn switch' the placeholders to the real files in
the shared files project
After you did that, the files are integral part of your tree, meaning
that changes to them will be committed with all other changes. Updates
will be received in normal updates.
I like to posit however that most 'shared files' scenarios (especially
with source files) indicate problems with the library split. Many
times, the shared files actually belong in a separate project with its
own (stable) API.

Right. I can only confirm that.
