Incomplete draft patch. It probably rejects too much and doesn't permit all
which is listed in comment 1.

------- Comment #1 from burnus at gcc dot gnu dot org  2010-06-01 07:39 -------
CONFIRM and no regression. Thanks for the report.

For the block data construct (F2008, 11.3) the compiler shall diagnose the
following constraints:

C1116 (R1120) A block-data specification-part shall contain only definitions of
derived-type definitions and ASYNCHRONOUS, BIND, COMMON, DATA, DIMENSION,
EQUIVALENCE, IMPLICIT, INTRINSIC, PARAMETER, POINTER, SAVE, TARGET, USE,
VOLATILE, and type declaration statements.

C1117 (R1120) A type declaration statement in a block-data specification-part
shall not contain ALLOCATABLE, EXTERNAL, or BIND attribute specifiers.
