Yes, you are right, when using 

> #+begin_src sh

It seems that I'm also running some bash shell! :-) Previously I was
using the src block in this way:

  #+begin_src shell

and here the shell seems to be com.exe.

But I'm not sure if I'm halfway there with "sh"?  I need to run the
following MSYS2 command AND switch between two arguments (for building

  \MSYS2\msys2_shell.cmd -mingw64


  \MSYS2\msys2_shell.cmd -msys.

How could I achieve this within a src block?
