-mno-cygwin is an obsolete command line option, formerly used for
cross-compiling from cygwin to mingw.  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.
