In gdb-4.5, a print of a zero length array ends up in error with the
following message : "Value not integer or pointer."

I think that, since gcc allows such structures, gdb should not
complain.

A fix could be to add in valprint() function :

      /* Arrays of zero length are OK, just print {} */

	  if (TYPE_LENGTH (type) == 0) {
	  if (arrayprint)
	    print_spaces_filtered (2 + 2 * recurse, stream);
	  fprintf_filtered (stream, "{}");
	  break;
	  }

      /* Array of unspecified length: treat like pointer to first elt.  */

Please give me your comments.

PS : The following shows the problem :

psi:/usr2/pierre:cat pw.c

struct FOO {
  unsigned int bar;
  unsigned int foo[0];
} xxx;

main()
{

}
psi:/usr2/pierre:gcc -v -g -o pw pw.c
