I guess you mean the C unlink, since I don't see the R unlink being
called.
Generally deletes fail on Windows when files are locked, e.g. open for
reading or writing. I haven't seen Windows file deletes fail in other
circumstances, so I suspect this was an R, MinGW or MSVCRT bug rather
than a Windows bug.
