It actually seems like is _isatty is defined in MinGW. I just tested a 
small program I found here:

    http://permalink.gmane.org/gmane.comp.gnu.mingw.msys/448

    #include <stdio.h>

    int main(int argc, char *argv[])
    {
      if (isatty(fileno(stdin)) && _isatty(fileno(stdout)))
        printf("interactive\n");
      else
        printf("batch\n");
      return 0;
    }

If I run this program in cmd.exe it says "interactive". I get the same 
result under MSYS and Cygwin. However running it in Emacs in shell:

    M-x shell

it instead says "batch". (This is in the CVS version of Emacs.) Is this 
what is expected?
