this does not apply directly to wine, but using that definition, a shared library
that contains only variables assignments (let's say it's a localization module),
would be considered "statically linked".  As for the latter, see next response
(linux threading model sucks).

so, given that linux's threading model creates a separate process per thread,
can call calls by the thread be considered a remote call?  Or in wine's case,
you're going to make a distinction between server dlls and client dlls ONLY
because they cross a process boundary?

If you think this is ugly, try applying this to java, where the concept of "file"
(since the classes can be in a zip file) an app (since there is no concept
of an 'executable' - just entry points), or even a 'process space' is vague.

section 5 is SUPPOSED to address this issue, but it depends on what people
think "small" means.

Guess it depends if you think LGPL is viral or not.....
