Hi. This is the qmail-send program at sources.redhat.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

   Can we have a posting to gcc-patches that describes this patch?
   
Please see optimization/4487 in GNATS.  Or:
