Indeed. Here's the new version. Bootstraps (with shared libgcc both
enabled and disabled) now running. I expect them to pass because I've been
through a couple of revisions tweaking this patch and they all passed.
Touches only Cygwin-specific backend target header. Assuming both
bootstraps succeed, OK for mainline?
