[Patch, Fortran, F08] PR 60357: structure constructor with unspecified values for allocatable components

[Janus Weil <janus at gcc dot gnu dot org>]

Hi all,

here is a small patch for an F08 extension: Allocatable components
don't have to be specified in structure constructors any more.

Regtested on x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
