Yes, it is, but in a standard MSYS installation we normally start it 
in `sh compatibility' mode.

Maybe; maybe not.  Depending on how your native MSW emacs invokes a 
shell, it may be just a matter of making the COMSPEC variable, (in 
the environment), point to the MSYS shell; try starting emacs from 
the MSYS shell itself, with a command such as:--

  $ COMSPEC=/bin/sh.exe path/to/emacs ...

(This should work, if emacs uses a `system()' call, resolved through 
MSVCRT.DLL, as would be the case if built using MinGW, or any other 
compiler suite which uses this, or a derivative runtime).

Huh?  Certainly, avoid RXVT like the plague; use a native Win32 
console, either standalone, or driven through Console2.

$TERM isn't really a good choice for identifying an MSYS environment, 
(it is too ubiquitous); something MSYS specific, such as $MSYSTEM, 
would surely be a better choice.
