I believe I did send everything to the mailing list. I may have copied you directly also. Apologies if that was inconvenient. > At that point I could reproduce your first mkshortcut issue.

Is it simply mis-reporting that there's an existing link file? Yes. The hint in the error message is unhelpful I think, since a missing directory is only one of a myriad of possible errors. As you note, an existing link prompts the same message. On the build I made on Windows 10, however, I hit the problem on the very first invocation. I imagine you therefore are building on Windows 7 or earlier, which seems to produce binaries that work OK. As I said, I suspect this is because IPersistFile::Save has changed semantics, e.g. per this link: https://msdn.microsoft.com/en-us/library/windows/desktop/hh848036%28v=vs.85%29.aspx I haven't verified this; I don't know how why or whether gcc is volunteering the executable to run in Windows 8 mode, or if there's a manifest in some dll library stub, or whether the COM ID of the IPersistFile interface is redirected by newer headers, or any similar variant of Windows black magic, but it seems to me like a good guess. If you're going to stay building on Windows 7 then, I don't think this latter patch is needed, although it's hopefully harmless. But I guess without it the code will silently break when Windows 8 or newer comes into the picture.
