A simple way I do this is to test for the existence of an environment
variable that gets set in .login such as NAME.  if it exists, then it is
most likely a sub-shell, otherwise, .login has not been executed yet, so it
should be a login shell.  This has worked for me so far under SunOS 3.x and
4.0.
