Thanks for the report, the same error happens on GNU/Linux. So I have

Hi

I'm using Emacs in the MSYS2 environment. And the local shell bash
depends on the order of its command-line switches.

When the last argument is "-i", bash starts normally.

    >C:/msys64/usr/bin/bash -norc -noprofile -i
    bash-4.4$

But in another case, it ends with an error.

    >C:/msys64/usr/bin/bash -i -norc -noprofile
    /usr/bin/bash: line 0: /usr/bin/bash: -noprofile: invalid option name

So I think we need the following patch to fix that.

Best regards,
Koichi Arakawa
