Hello,
A post to R-Help by Oliver Soong reports what seems to be a bug
specific to Windows (I'm on Windows 7).
The original post is as
warning(_("cannot link '%ls' to '%ls', reason '%s'"),
from, to, formatError(GetLastError()));
}
#else
But there's something going on. The link is not created and the warning
message is wrong.
Bug report? (Why CreateHardLinkW, and not CreateHardLink?)
