[Bug c/21275] New: gcc 4.0.0 crash with mingw when using stdout in global var

[ch dot ehrlicher at gmx dot de]

This small piece of code doesn't work with gcc 4.0.0, but with 3.4/3.3:

-----------------------------------------
#include <stdio.h>
#include <stdlib.h>

FILE* out = stdout;

int main( int argc, char **argv )
{
//  out = stdout; // this is ok
  return 0;
}
-----------------------------------------

Here the output:
C:\tmp>gcc main.c
main.c:4: error: initializer element is not constant

C:\tmp>g++ main.c
main.c:9: internal compiler error: output_operand: invalid expression as operand

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Here is reduced testcase:

// int attribute ((dllimport)) foo;
extern int* _imp__foo;
int a = *_imp__foo;

Oops, I reduced the code in comment #1 too much.  This shows the problem.  

//dllimport_array.C

// This causes 'initializer element is not constant' error in C,
// static_initialization_and_destruction code in C++
extern __attribute__ ((dllimport))  int* foo1;
int* k = &foo1[0];

// This causes 'initializer element is not constant' error in C,
// ICE in C++
extern __attribute__ ((dllimport))  int foo2[];
int* j = &foo2[0];

I think this is a dup of bug 21081.

I think DECL_NON_ADDR_CONST_P is set too late.
Regtesting a patch that fixes 21081 and this.

Can or will this patch be put into mainline?  Seems to be falling in a crack. 
It is needed to help with moving forward on pr23138.  I will apply the patch
given here.  My first attempts failed, maybe I have to do it manually.
