* Copies path for unix sockets on Windows NT.

|

* This function does the following chores:
|

*
|

* 1. Fixing drive letter paths, e.g. `/c/` → `c:\`
|

* 2. Turn `/tmp` into GetTempPath()

* I don't think we need normalize the path here.

|

* @return short count excluding NUL on success, or -1 w/ errno
