I compared strace's on b20.1 and 1.1.2 and the shared argument to
CreateFileA has changed.  FILE_SHARE_DELETE was dropped from
host_dependent.shared in dcrt0.cc (host_dependent_constants::init).
This was the comment at the time:

        * dcrt0.cc (host_dependent_constants::init): Eliminate DELETE flag
        from shared constant.

I put it back and your test program works again.  Perhaps Chris can
shed some light on the reason for the change.
