I use:

# File: cmd
`cygpath "$COMSPEC"` "$@"
and
#!/usr/bin/env bash

# https://sourceforge.net/p/cygsimple
# File: start
cmd /c start `cygpath -w -- "${@//&/^&}"`
The file /usr/local/bin/start uses the file /usr/local/bin/cmd because
of PATH.
I use another such file to start the Windows version of gvim.
#!/usr/bin/env bash
# Copyright (C) 2018, cygSimple

export PATH=/c/opt/vim/vim74:"$PATH"
start /c/opt/vim/vim74/gvim `cygpath -w -- "$@"` &
So what else does cygstart do that I might setup
before a "cmd /c"
to get the target to run?
Don't know.
Or anyway to have cygstart run the command with its output in the
current window?
A windows program will have a different console by default. A console
program could can communicate to the same console as it is started in
unless it uses pty (e.g. /c/windows/system32/ftp).

START - Starts a separate window to run a specified program or command

If it's a console cmd it should run under a term without any problems:
$ cmd /c ver
Microsoft Windows [Version 10.0.17134.471]
or you may need to use https://github.com/rprichard/winpty - allows running
Windows console programs under mintty or Cygwin's sshd with properly-functioning
input and output by starting winpty-agent with a hidden console window, which
bridges between the console API and terminal input/output escape codes, polls
the hidden console's screen buffer for changes and generates a corresponding
stream of output.
