1.3.3 Fortran 2008 status

The GNU Fortran compiler supports almost all features of Fortran 2008; the wiki has some information about the current implementation status. In particular, the following are not yet supported:

• DO CONCURRENT and FORALL do not recognize a type-spec in the loop header.
• The change to permit any constant expression in subscripts and nested implied-do limits in a DATA statement has not been implemented.
