I don't know what the issue is.  When I execute that command from my 
normal bash shell, it works just fine.  This is current Cygwin, so:

qemu$ sed --version
sed (GNU sed) 4.4
Packaged by Cygwin (4.4-1) ...
qemu$ /bin/sh --version
GNU bash, version 4.4.12(3)-release (x86_64-unknown-cygwin) ...

Perhaps I misread the sed manual, but I thought when you used a character 
other
than "/", you had to preface the character with a backslash, e.g., 

   sed 's\,.*,,;'

But, the above is all just speculation.  I don't know what the real 
problem is.

FWIW, I rebuilt twice more and the error didn't show up again, but I did
get some other spurious errors, one from GCC "invalid argument" and 
another:

/bin/sh: /usr/bin/x86_64-w64-mingw32-gcc: Device or resource busy
make: *** 
[/cygdrive/c/scm/Deos/products/qemu/branches/2.12/output/qemu-2.12.0-rc2/rules.mak:66:
 
stubs/notify-event.o] Error 126

So perhaps it is just normal Cygwin "fork" errors, or my use of "make 
-j8".

I think you can ignore this.  Sorry for the spam.
