/* This test demonstrates a failure to resolve opaque structure types in
   binaries compiled by the Intel C compiler.  This is GDB PR symtab/13277.

   The test was derived from opaque-pointer.c, which contains the single line:

   struct opaque_struct_t *p_struct;

   and opaque_struct.c, which looks like:

   struct opaque_struct_t
   {
     int wrapped_value;
   };

   struct opaque_struct_t opaque_internal = { 0 };

   What follows is a simplified version of the debug info generated by ICC
   version 12.0.4.191. */
