No, I found the solution by getting the double-plus surprising result
that removing these hardlinks works in Cygwin 1.5. For some reason only
the OS hackers at Microsoft might grok, setting the delete dispostion
flag for a file (*) doesn't work, but opening the file with the
FILE_FLAG_DELETE_ON_CLOSE flag and then closing it again (**) works
fine. Go figure! Unfortunately the DELETE_ON_CLOSE stuff is too
dangerous in some circumstances so it's not a generic solution.
I'm preparing a fix for 1.7.

(*) Which is also what the Win32 function DeleteFile does.
(**) Which is what Cygwin 1.5 and the native function ZwDeleteFile does.
