[Patch, fortran] PR68846 - Pointer function as LValue doesn't work when the assignment regards a dummy argument.

[Paul Richard Thomas]

Committed as obvious in revision 260113.

I will commence backporting as soon as I can.

Thanks to Mirco Valentini for the initial fix, which he posted on 2017-02-28.

Cheers

Paul
