+#define GFC_STD_F2008  (1<<7)  /* New in F2008.  */
 #define GFC_STD_LEGACY (1<<6)  /* Backward compatibility.  */
 #define GFC_STD_GNU    (1<<5)  /* GNU Fortran extension.  */
 #define GFC_STD_F2003  (1<<4)  /* New in F2003.  */

I fear this will break some std tests. You should better use:

 #define GFC_STD_LEGACY (1<<7)  /* Backward compatibility.  */
 #define GFC_STD_GNU    (1<<6)  /* GNU Fortran extension.  */
 #define GFC_STD_F2008  (1<<5)  /* New in F2008.  */
 #define GFC_STD_F2003  (1<<4)  /* New in F2003.  */

which is also more readable - especially when we will have F2013 etc.

decl.c also contains two STD_F2008: "Fortran 2008 draft allows BIND(C) for
internal procedures.".

Additionally, one needs to update *texi for the new -std=f2008 option.

Also the .F08/.f08 should be supported, cf.
http://gcc.gnu.org/ml/fortran/2007-01/msg00410.html
and note that also the CPP section has to updated.
