Launch Emacs for Windows with Batch File using Emacs Configuration from Cygwin

I maintain a shared Emacs configuration under Linux and Cygwin. In Windows, I wanted to easily launch Emacs from the Desktop with the following goals.

• Create a shortcut in the taskbar that launches Emacs for Windows
• Have Emacs for Windows obey the Emacs configuration from Cygwin
• Avoid opening extra console windows

Some prerequisites,

• I'm running Emacs for Windows from https://ftp.gnu.org/gnu/emacs/windows/.
• I'm running Cygwin64 in c:/cygwin64, although this works for 32-bit Cygwin as well.

I created a file called c:\cygwin64\emacs.bat with the following contents.
c:\cygwin64\bin\run bash.exe -c ~/dotfiles/bin/emacs.sh

The file ~/dotfiles/bin/emacs.sh is a shell script that sits in my Cygwin directory. It is a wrapper script that calls Emacs for Windows if I'm running Cygwin.

It is assumed that the default Emacs configuration sits in the ~/.emacs file under Cygwin.

Pin the c:\cygwin64\emacs.bat script to your task bar. See below if you do not know how to do this. Clicking on it will open Emacs for Windows without any intervening console windows.
