Dear all,

PR 50981 is about passing an absent argument to an elemental procedure.

a) Passing an absent optional dummy as actual.
4.4-4.7 Regression, fixed for 4.7; backporting pending.

b) Passing an unallocated allocatable or not associated pointer as actual
F2008/GCC 4.6 feature. Fixed by this patch.

c) Handling polymorphic scalars/arrays with elemental procedures
Some draft patch available, but needs more work. That's a 4.7/4.8 item.

The attached patch solves (b).

Build and regtested on x86-64-linux.
OK for the trunk? (And [together with (a)] for the 4.6 branch?)
