New information on this issue:

mingw-runtime 3.15 (2008-09-07) added support for
standard format conversion:

http://sourceforge.net/project/shownotes.php?release_id=24832

The release note also says how to select MS or C99/POSIX
format strings.

Debian still does not include that version:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=498529

Maybe someone knows how we can help to get the new release
for debian. It's needed for cross compilation (at least for
users who don't want to install it manually).

Good question. I don't know because I did not try it.
It was only a guess that qemu would not work with
mingw-w64 without modifications.
