=============================================================================
[Start of bug report]
In emacs 27.1, the command:
   emacsclient -a '' -c  & 

Doesn't anymore start emacs as a daemon server. This is critical,
because many people use emacsclient in this manner to optionally start
the server if it doesn't exist, and simply connect to it if it's already
running. Please fix this, or at least backout the changes that broke
emacsclient.

Not on Cygwin, it seems.  This appears to be a Cygwin-specific
problem.

I believe this was recently fixed for the upcoming Emacs 27.2.  If you
can build the latest emacs-27 branch of the Emacs Git repository, I
think you will see that the problem is gone.

There was no response within a month, so I'm closing this bug report.
If the problem still exists, please respond to this email and we'll
reopen the bug report.
