Thanks for all these explanations.

So, I will continue to put fixes regarding i686-pc-mingw32 into gnulib,
whereas when we find bugs for i686-w64-mingw32, it seems we should better
report them at <https://lists.sourceforge.net/lists/listinfo/mingw-w64-public>
or <http://sourceforge.net/tracker/?atid=983354&group_id=202880&func=browse>.
