It is NOT used when building for cygwin, and these days, building for mingw should use a proper cross compiler (available from cygwin.com) rather than the -mno-cygwin crutch. To me, this means that there is some cruft in the configure file, and that no one has ever really tried to port qemu to cygwin yet. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
