compiz - Apr 2007 - RTLD_GLOBAL flag for dlopen

I am just experimenting with a plugin loader and I found
that there are problems with external symbols which are
loaded at runtime.

The solution is to add RTLD_GLOBAL to the dlopen mode,
but I am not sure if this would cause other problems.

Is this patch OK to go in?

So your plugin loader provides symbols that subsequently loaded plugins
use? What are those symbols and what are they used for? Maybe there's a
more appropriate way to provide those symbols to the plugins.
