Sure, that will help fixing Wine alignment bugs. But an MSVC source
that makes assumptions about the alignment of __int64, when recompiled
as a Winelib app with GCC could still prove to be very hard to debug.

So it's important to find a way to make all 64 bit types align on 8
byte boundaries, like MinGW does as well. We have to do it selectively
of course, because Unix libraries have different assumptions about the
alignment of 64 bit types.
