[Patch, fortran] PR38917 and PR38918 - DATA and pointers

Subject: [Patch, fortran] PR38917 and PR38918 - DATA and pointers

We were not doing very well with DATA and pointers up until now.  This
patch fixes that.  As it happens the fix is trivial/obvious.

Bootstrapped and regtested on FC9/x86_64 - OK for.... trunk/4.5?

The reason that I ask is that this patch is highly unobtrusive.. it's
even right:.  Also, if we are honest, there are not many users of this
corner of f95:-)

I would like to take this opportunity to thank the reporter, Dick
Hendrickson.  Not only has Dick been a frequent reporter of gfortran
bugs but.... well, let me say that he gives us free indirect access to
a bug finding resource and reduces the bugs beautifully - Thanks,
Dick!

Cheers

Paul
