Subject: openbsd patches
- The dlsym() one is supposed to fix dynamic loading on our a.out
architectures, where prefixing of an underscore symbol is required.
Actually I don't know what kind of dynamic loading does SDL deal with,
but anyway. You may want to make that change global, but only gcc's
preprocessor passes __ELF__, I think, so you can just add Linux or
something if you decide so.
