Windows has a concept of shortcuts (.lnk files).  Cygwin's ln creates a 
shortcut to simulate a symbolic link.  MSYS implements 'ln -s' by doing 
a file copy.  I don't think it works for directories.

I'm not personally opposed to just getting rid of 'qemu' for the 0.11 
release.  Sure, there will be some management tools that look for 'qemu' 
instead of 'qemu-system-i386' but I doubt they'll change things until 
the symlink goes away.

We can issue a big fat ANNOUNCE to the mailing list that for 0.11 the 
executable name will change.  Since it won't be for a few months, that 
should give people time to adjust.
