This patch adds checks to reject this.
Please try to come up with things which should be rejected; I think
there are none, but I still might have missed something. ;-)
Build and regtested on x86-64. OK for the trunk?
PS: I did not check the standard, but ifort and NAG f95 reject it. As it
makes sense, I believe these compilers. If needed be, I can still try to
find it in the standard.
