[EXTERNAL] Re: Cygwin 3.3.4 - cmd to symlinked path doesn't work

[BRISLANE Mark]

Hi there,

I wonder if this is OS dependent? I note you're on Windows 7 / Server 2008 R2 (both EOL by the way!) where as I'm on Windows Server 2016.

The server where this works on an older version of Cygwin is Server 2012 R2, and I've copied the cygwin1.dll from that server to my Server 2016 server but the issue still happens.

Regards,
Mark

The interesting part is that the behavior is dependent on sequence of events.

`mintty bash -i` in a directory:

> $ pwd
> /cygdrive/d/cygwin
