From: Peter Valchev <pvalchev@openbsd.org> 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.
