There are several constructs in fortran 77 that have been removed from
fortran 95 (PAUSE, ASSIGN, H descriptor, noninteger loop variables, etc).
I originally planned on not supporting any of these at all, but on
requests and reflection, we're going to add error messages that tell the
user that some feature is no longer in fortran 95, rather than an
"unclassifiable statement" error. Niels Jensen has already started
working on this.
