Includes information for the ISO_10646 character set and the restricitions on unlimited polymorphic variables.

ISO_10646 Character Set

The Fortran 2003 features related to supporting the ISO_10646 character set are not supported. This includes declarations, constants, and operations on variables of character(kind=4) and I/O operations. Support for this feature is optional in Fortran 2008.

Restrictions on Unlimited Polymorphic Variables

Unlimited polymorphic variables whose dynamic types are integer(1), integer(2), logical(1), or logical(2) are not supported, unless the -d h is specified to disable packed storage for short integers and logicals.
