[PATCH, Fortran] Extend F2003 structure constructor support

[Tobias Burnus]

Sorry, I forgot to change the command line for mutt's -s subject.

My reply to this patch (http://gcc.gnu.org/ml/fortran/2008-05/msg00110.html)
is thus in previous email titled

"Re: [PATCH, fortran] Interoperability with C int128_t types"
http://gcc.gnu.org/ml/fortran/2008-05/msg00147.html

Sorry for the confusion.

Tobias
