Comment (by Gedare):

 Very ugly. The hack might be a bit more clear if we use

 {{{

 typedef struct {
   Heap_Information_block workspace_info;
   Heap_Information_block heap_info;
   uint32_t active_posix_key_value_pairs;
   union {
     uint32_t anonymous[ 1 + ( sizeof(rtems_resource_rtems_api) +
 sizeof(rtems_resource_posix_api) ) / sizeof(uint32_t) ];
     struct {
       uint32_t active_posix_keys;
       rtems_resource_rtems_api rtems_api;
       rtems_resource_posix_api posix_api;
     }
   }
   int open_files;
 } rtems_resource_snapshot;
 }}}
