Hi,

qemu-img doesn't work on MS Windows, when compiled with MinGW Runtime 
package >= 3.15
According to 
http://sourceforge.net/tracker/index.php?func=detail&aid=2222263&group_id=2435&atid=102435 
, qemu-img shouldn't skip the first argument (command name) by doing 
optind++.

Attached patch fixes the problems, and repairs qemu-img parsing with 
MinGW Runtime package >= 3.15
