Fix Clang warnings on Windows

- Align DLLEXPORT in definitions and declations. There is still a few
  cases left, where the declation in the compiler's complex.h disagrees
  with the implementation here. For now we can't do anything about that,
  but maybe should be revisited in the future.
- Fix the syntax on an .ascii directive that gcc accepted mistakingly, but
  clang does not.
