  using a different callvm for .dyncall that may be setup via prefixes and
  resets to default always.

- handling of Csingle attribute on double vectors
- character encoding support, R supports UTF-8.
- Fortran calling conventions
- attr("struct") -> attr("CType")
- parseStructInfos -> cstruct
- parseUnionInfos -> cunion
- .dyncall typed pointer

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
