The last patch to RCS was triggered by some wierd network redirector which
returns error code 2 (file doesn't exist) when you try to rename a file on
a networked drive and the target of the rename already exists (we expect
DOS to return code 5: access denied).  The following patch to `_rename' 
fixes that problem and makes the patch to RCS unnecessary:
