I've been using the GNULIB poll() impl in libvirt on Win32 (well Mingw + WINE) and found it was producing really wierd results, such ret=-1 + errno=EAGAIN, or ret=0 even though requested timeout was infinite. After a little debugging I discovered a missing initialization of the 'rc' variable in the Win32 impl of poll(). With this patch applied, it is behaving as desired.
