Dear All,
This is another corner of a corner case that is not a regression but
fixes a wrong-code-on-valid.
At present, an actual argument of an elemental procedure with the
VALUE attribute is not passed by value. The fix is obvious.
Bootstraps and regtests on FC17/x86_64 - OK for trunk, 4.8 and 4.7?
Cheers
Paul
