#1963 MSYS needs to find "$COMSPEC" binary.

[Earnie Boyd]

MSYS needs to support the following scripts.

$ cat /bin/cmd

#!/bin/sh

# This file is part of Minimal SYStem.
#   http://www.mingw.org/msys.shtml
# File: cmd

"$COMSPEC" "$@"

$ cat /bin/start

#!/bin/sh
# Copyright (C) 2002, Earnie Boyd
#   mailto:earnie@users.sf.net
# This file is part of Minimal SYStem.
#   http://www.mingw.org/msys.shtml
# File: start

cmd //c start "$@"

The current result of
$ start /msys.bat MSYS

cygwin warning:
  MS-DOS style path detected: /usr/local/bin/C:\Windows\system32\cmd.exe
  Preferred POSIX equivalent is: /usr/local/bin/C:/Windows/system32/cmd.exe
  CYGWIN environment variable option "nodosfilewarning" turns off this warning.
  Consult the user's guide for more details about POSIX paths:

/usr/bin/cmd: line 2: C:\Windows\system32\cmd.exe: command not found

• /usr/local/bin should not have been prefixed to C:\Windows\system32\cmd.exe.
• MSYS2 needs to be able to operate on \ path delimiters.
• See [#1962].
• Paths to http://cygwin.com need to be modified to use http://mingw.org/wiki or removed.

I believe there may be a bug with /bin/start; the invocation of cmd /c should accept a single argument which is the entire command string.

So the implementation:

cmd //c start "$@"

Should be:

cmd //c "start $@"

While start notepad works with both implementations, passing additional arguments to start such as /wait only works with the second implemetation. Specifically,

$ start /wait notepad

The current implementation returns a Windows dialog message stating that the file C:/MingGW/msys/1.0/wait cannot be found.

The scripts are already available in MinGW so I'm not sure what this issue is tracking, but since it's open it seemed a good place to start. I can file a separate issue if you prefer or make a pull request if you could point me to the source.
