Any idea why it tries to access a file called //xmined?  The double
slash at the beginning indicates a network UNC path.  So what Cygwin
does is trying to access a server called xmined on your network.
And later on...

...quite apart from this weird error 487 which still requires
investigating...

...it tries to access a server //minmacs.
