Bug Description

Unresolved symbols in plugins cause compiz to exit instantly (appears to crash);
./bin/compiz: symbol lookup error: lib/compiz/libcomposite.so: undefined symbol: _Z31this_function_does_not_exist_tmv

Obviously, compiz should either;
  (a) Gracefully refuse to load plugins that have unresolvable symbols;
  (b) Treat unresolved symbols as errors at build time;
  (c) All of the above.

I have tried (b) before but it seems to require non-trivial work to be done on various plugins. Fixing (a) however appears trivial.
