Some Windows version expect output to be aligned on 4 bytes.

Notes (from i386 and x86_64 tests):
- MSVC and Mingw/gcc don't layout the two variables (sdki, sdki_ex)
  the same way.
- MSVC aligns each variable on 4-byte boundary,
- MingW/GCC stores them in a 8-byte chunk, but starting from the
  end of the buffer: hence none of them is on a 4-byte boundary.

So, fixing the alignment of variables is not sufficient to
workaround the compilers' discrepancy on all source code.

I didn't find a generic way to align on 4 bytes structures of size
smaller than 4 bytes (apart from adding the DECLSPEC_ALIGN to
each of the offending structures, likely not that many though).
Ideas welcomed.
