[Patch, Fortran] PR 38415: procedure pointer assignment to abstract interface

[Janus Weil]

Hi all,

this is a very simple patch for a small accepts-invalid problem with
procedure pointers that was recently reported by Tobias (thanks for
finding this!). The patch is really trivial, and I'd say it's
reasonable to still include it in 4.4. But of course I'll leave that
decision to the reviewers. It's regtested on i686-pc-linux-gnu, and I
think one can be sure that it doesn't introduce any new regressions.
Ok for trunk/4.5?

Cheers,
Janus
