+- character encoding support, R supports UTF-8.
+- Fortran calling conventions
+- attr("struct") -> attr("CType")
+- parseStructInfos -> cstruct

+BUGS:
+- OpenBSD 4.8/amd64: SDL failed due to pthread.
+  R version on OpenBSD does not provide a shared R library, thus
+  the symbols are not resolvable.
+  Additional Test for resolving self:
+  While .dynsym(as.extptr(NULL), "R_ShowMessage") works on Mac OS X, it fails on OpenBSD.
+- demo(ttf) failed on Mac OS X 10.6
